Constitutivism argues that the source of the categorical force of the norms of rationality and morality lies in the constitutive features of agency. A systematic failure to be guided by these norms would amount to a loss or lack of agency. Since we cannot but be agents, we cannot but be unconditionally guided by these norms. The constitutivist strategy has been challenged by David Enoch. He argues that our participation in agency is optional and thus cannot be a source of (...) categorical demands. In this paper, I defend the viability of constitutivism by showing that agency is indeed a special ‘inescapable’ enterprise. Agency has the largest jurisdiction, and it is closed under rational assessment. This inescapability does not exempt constitutivism from raising the question whether agents have reason to be agents, but this question has to be taken up within agency. If this question is answered affirmatively, then—I argue—the criteria of practical correctness are self-ratifying in a non-circular way. This is sufficient to show the viability of the constitutivist strategy. Whether agents have conclusive reasons to be agents, however, is a matter to be addressed in the terms of particular versions of constitutivism. (shrink)

It is often argued that future-directed decisions are effective at shaping our future conduct because they give rise, at the time of action, to a decisive reason to act as originally decided. In this paper, I argue that standard accounts of decision-based reasons are unsatisfactory. For they focus either on tie-breaking scenarios or cases of self-directed distal manipulation. I argue that future-directed decisions are better understood as tools for the non-manipulative, intrapersonal division of deliberative labor over time. A future-directed decision (...) to ϕ gives rise to a defeasible exclusionary reason to ϕ. This reason is grounded on the default authority that is normally granted to one’s prior self as an “expert” deliberator. I argue that this kind of exclusionary reason is the only one that can account for the effectiveness of future-directed decisions at shaping our diachronic agency without violating our autonomy over time.

In this paper, I will discuss the various ways in which intentions can be said to be conditional, with particular attention to the internal conditions on the intentions’ content. I will first consider what it takes to carry out a conditional intention. I will then discuss how the distinctive norms of intention apply to conditional intentions and whether conditional intentions are a weaker sort of commitments than the unconditional ones. This discussion will lead to the idea of what I call (...) the ‘deep structure’ of intentions. Roughly, this is the idea that the conditional nature of our intentions is only partially made explicit in the expressions we use to communicate our intentions and in the explicit form of our thinking about and reasoning with them. Most conditions that qualify our intentions are part of a deep functional structure that can be evinced by observing the actual psychological functioning of intentions and by considering the rational requirements that they engage. I will argue that the deep structure of intentions is characteristically conditional. Genuinely unconditional intentions are only limiting instances of conditional intentions and their contribution to agency can only be understood in light of this fact. I will conclude by showing that the characteristic conditional structure of intentions is intimately related to distinctive features of human agency, especially to its unity over time. (shrink)

In this paper I investigate whether there are genuine and irreducible pressures of diachronic rationality grounded on the structure of the subject rather than on substantive considerations, such as pragmatic ones. I argue that structural pressures of diachronic rationality have a limited scope. The most important pressure only tells against arbitrary interference with the mechanisms for the retention of attitudes over time. I then argue that in the practical case, a substantial account in terms of the agent's temporal identity appears (...) more promising than a purely structural one, but in the end it still leaves many questions about diachronic practical rationality underdetermined. (shrink)

This chapter discusses the structure of our temporally extended agency. We do not have the power to act directly at a distance, so any of our temporally extended projects must be sustained over its temporal unfolding by momentary actions. We need both the capacity to organize these momentary steps in light of a synoptic overview of the extended activity as a whole and to sustain our motivation to continue to pursue the extended activity. Hence, the distinctive mode in which we (...) act over time is that of ’planning agency,’ which requires a form of temporal identification that goes beyond mere psychological continuity. I then discuss the differences in internal structure between merely continuous and integrated activities, and between telic and atelic ones. I provide a taxonomy of the different kinds of temporal goods and values and how these structures might bear on the risk of crisis of meaning in our temporal existence. I then touch briefly on the issue of how our mortality might make a difference to the structure of what we find valuable and how it relates to the temporal features of our agency. In the closing section, I discuss the effects of the moving temporal location of the agent (with her local executive powers) relative to her extended pursuits, including the asymmetries generated by the distinction between past and future stages of the activity and the moving horizon of what the agent can anticipate and (indirectly) control.

In this paper, I discuss whether there are genuinely *diachronic* constraints of practical rationality, that is, pressures on combinations of practical attitudes over time, which are not reducible to mere synchronic rational pressures. Michael Bratman has recently argued that there is at least one such diachronic rational constraint that governs the stability of intentions over time. *Pace* Bratman, I argue that there are no genuinely diachronic constraints on intentions that meet the stringent desiderata set by him. But I show that (...) there are at least two synchronic rational constraints with distinctive and important, although only indirect, diachronic dimensions. Neither of them, however, supports the practical conservatism in the face of normative underdetermination that, according to Bratman, is part and parcel of the diachronic rationality of intention stability. (shrink)

In this paper, I argue against the popular philosophical thesis---aka the ‘own action condition’---that an agent can only intend one’s own actions. I argue that the own action condition does not hold for any executive attitude, intentions included. The proper object of intentions is propositional rather than agential (‘I intend that so-and-so be the case’ rather than ‘I intend to do such-and-such’). I show that, although there are some essential de se components in intending, they do not restrict the content (...) of intentions to one’s own actions. I then discuss the special way in which one’s own actions can figure in the content of one’s intentions, which shows that the distinction between intending and acting is less stark than it appears at first. This is a conclusion that many defenders of the own action condition might find appealing but which, I argue, is better supported by rejecting the own action condition. (shrink)

This paper offers an overview of the ways agents might extend over time and the characteristic structure of extended human agency. Agency can extend in two distinct but combinable modes: the ontological, which gives rise to simple continuous agents; and the conceptual, which gives rise to agents who conceive of and care about distal times, and have minimal planning abilities. Our extended form of agency combines both. But we are still limited by the temporal locality in the operation of our (...) psychological and executive powers. To account for this locality, I introduce the notion of 'temporal selves,' as the loci of immediacy in the agent's determination of their psychology, conduct, and practical standpoint. I argue that the passage of time generates, by itself, the threat of temporal alienation from distant temporal selves. A genuinely extended agency requires temporal identification: the sharing, by separate temporal selves, of a temporally extended and integrated practical standpoint. This temporal identification cannot be produced simply by temporal identity as continuity. What is required is temporal identity in the mode of unity and integration. This identity does not precede temporal identification but is co-constituted with it. I offer a preliminary account of the structure of the units of integration for agents who aspire to persist in the mode of unity and integration. I close with a cautionary note: the complex structure of integration, although familiar in everyday life, is often missed by standard philosophical accounts, which tend to focus on simple models of extended agency.

There are two standard conceptions of the functioning of and rationale for the diachronic will, i.e., for an agent's capacity to settle on her future conduct in advance. According to the pragmatic-instrumentalist view, the diachronic will benefits us by increasing the long-term satisfaction of our rational preferences. According to the cognitive view, it benefits us by satisfying our standing desire for self-knowledge and self-understanding. Contrary to these views, I argue for a constitutive view of the diachronic will: the rationale for (...) it is that it makes possible to engage in activities with a radically novel temporal structure, activities that are not merely continuous over time, but temporally integrated and unified. These activities are essential to our form of life and to our existence as temporally unified agents. The instrumental and cognitive benefits, if any, are merely secondary to the ontological ones. (shrink)

I investigate the structure of pro-tempore disjunctive intentions: intentions directed at two or more eventually incompatible goals that are nonetheless kept open for the time being, while the agent is waiting to acquire more information to determine which option is better. These intentions are the basic tool for balancing, in our planning agency, rigidity and flexibility, stability and responsiveness to changing circumstances. They are a pervasive feature of intentional diachronic agency and contribute to secure dynamic consistency in our plans. I (...) show how they differ from simple disjunctive intentions, where the agent is indifferent between the options. I argue that pro-tempore disjunctive intentions meet the distinctive pressures of intentions and that, contrary to the initial impressions, they are both stable and successful at settling practical matters. In closing, I argue that pro-tempore disjunctive intentions are all-out intentions that are more explanatorily powerful than Holton's "partial" intentions. (shrink)

It is often argued, most recently by Samuel Scheffler, that we should reconcile with our mortality as constitutive of our existence: as essential to its temporal structure, to the nature of deliberation, and to our basic motivations and values. Against this reconciliatory strategy, I argue that there is a kind of immortal existence that is coherently conceivable and potentially desirable. First, I argue against the claim that our existence has a temporal structure with a trajectory that necessarily culminates in an (...) ending. This claim is based on two false assumptions: that a life as a whole calls for narrative structure, and that narratives necessarily require closure as temporal endings. Second, I reject the proposal that temporal finitude is constitutive of the basic elements of diachronic agency, including the nature of deliberation and of our values. I argue that only finitude as scarcity of opportunities is constitutive of these elements. Additionally, scarcity might be present in an endless existence. Therefore, it is not incoherent to conceive of a recognizable and potentially desirable immortality that grounds the core features of diachronic agency. Thus, against the reconciliatory strategy, I conclude that we might never fully reconcile with mortality. Although we might embrace our inescapable mortality as essential to a fuller range of features of our existence, we can still justifiably regret our missing on an immortal existence. (shrink)

There are three ways to control our future conduct: by causing it, by manipulating our future selves, or by taking future-directed decisions. I show that the standard accounts of future-directed decisions fail to do justice to their distinctive contribution in intentional diachronic agency. The standard accounts can be divided in two categories: First, those that conflate the operation of decisions with that of devices for either physical constraint or manipulative self-management. Second, accounts that, although they acknowledge the non-manipulative nature of (...) decisions, offer too restrictive a view of source of their effectiveness over time. I argue that a comprehensive view of decisions must acknowledge that there is a variety of ways in which they can be effective, which range from the exercise of rational authority to the reliance on sub-agential psychological propensities. What keeps all of these mechanisms together as possible explanations of the role of decisions in supporting diachronic intentional agency is that these mechanisms operate under a common regulative ideal of diachronic agency: the agent’s reliance on the continuous sense of the stability of the choiceworthiness of the action, regardless of her prior decision to perform it. In light of this regulative ideal, the contribution of effective decisions to diachronic agency is thus in principle dispensable although usually necessary for limited beings like us. (shrink)

This chapter presents Davidson’s account of intentional action and intention. Davidson initially discusses intentional action in relation to the explanation and the ontology of action. His earlier view equates acting intentionally with being caused to act by a pair of appropriately related mental states (a pro-attitude and an instrumental belief) and denies the existence of intentions as distinct mental states. Later, in his account of weakness of will, Davidson offers a more complex account of practical deliberation in terms of evaluative (...) judgments. Finally, in "Intending", Davidson discusses intentions for future action and argues that intentions are all-out evaluative judgments, reversing his earlier position about the non-existence of intentions as distinct and irreducible mental states.

In this paper, I discuss Ludwig's systematic and illuminating account of conditional intentions, with particular reference to my own view (presented in "Conditional Intentions", Noûs, 2009). In contrast to Ludwig, I argue that we should prefer a formal characterization of conditional intentions rather than a more substantial one in terms of reasons for action (although the conditions that qualify an intention bear on the reasonableness and justifiability of the intention). I then defend a partially different taxonomy of the conditions that (...) might qualify an intention and discuss how the difference bears on the application of the rational pressures of intention. I go on to acknowledge that Ludwig is correct on insisting on the centrality of the *epistemic* element in the antecedent of conditional intentions. But I argue that even when a condition has been settled (that is, when the agent has ascertained that it holds), the intention remains genuinely conditional. In my view, conditions that have been settled are not just part of the background of planning: they continue to qualify the content of the intention (although they come to play a different role when settled). I then discuss how the settling of a condition does not interrupt the *continuity* of the content and structure of the intention---in contrast to Ludwig's account, where the conditional intention appears to give rise, when the conditions are taken as settled, to a distinct *unconditional* intention. I close by discussing the serious concern that my way of characterizing conditional intentions threatens to swallow most intentions, given that it is unlikely that we have intentions that do not rest on our accepting the obtaining of relevant conditions.

An introductory survey of the contemporary philosophy of action.

Moral constitutivism purports to explain moral normativity by appeal to the nature of either agency or rational powers. Ambitious constitutivism aspires to ground the categorical authority of morality and to derive the content of the basic moral norms while avoiding the problems of moral realism. As a general strategy, moral constitutivism faces three serious challenges. First, the shmagency challenge. The worry is that the authority of the norms derived from the nature of agency is only conditional on having a reason (...) to be an agent rather than some other kind of subject, a shmagent or an alienated agent. Constitutivists usually reply by appealing to the inescapability of agency. Second, there is a worry that agency is too thin a basis for the derivation of the substantive content of moral norms. Finally, there is the worry that constitutivism might be unable to make room for bad actions. The entry considers possible responses by moral constitutivism to these concerns and whether, if these responses are unsatisfactory, moral constitutivism might still have some explanatory power but of a less ambitious sort.

In his book Willing, Wanting, Waiting Holton defends a comprehensive view of the will. His central claims are: that we have a capacity of choice, independent of judgment about what is best to do, that resistance to temptation requires a special kind of intentions, resolutions, and the exercise of an executive capacity, willpower, there is a distinction between weakness of will and akrasia. I argue that Holton is right about these claims, but I raise a few concerns: I am unclear (...) about the philosophical import of ; I find that important details in the explanation of the working of willpower vis-à-vis temptation are missing and that there are inconsistencies in his account of addiction; I would have liked a more extensive discussion of other possible defects of will; I am unclear about the scope of the will and the relation of willpower to other executive capac­ities. I conclude with a brief assessment of the contribution of psychological studies to the philosophical investigation of intentions and the will. (shrink)

I respond to Ferrero’s comments on “What are Conditional Intentions?” in three parts. In the first, I address three arguments Ferrero gives for his account and against mine, the argument from requirement of a formal distinction, the argument from continuity, and the argument from the rational pressures of intention. In the second, I raise some problems for Ferrero’s views on the basis drawing out its consequences and testing those against cases. In the third, I consider in a (...) more theoretical vein how reasons and intentions are related, and offer an explanation of why we should not read reasons for intentions into their contents.

Suppose that you intend to go to the theater. Are you therein intending the unconditional proposition that you go to the theater? That would seem to be deeply irrational; after all, you surely do not intend to go if, for instance, in the next instant an earthquake is going to devastate the city. What we intend we do not intend ‘no matter what,’ it is often said. But if so—how can anyone ever rationally intend simply to perform an action of (...) a certain kind? In response to the puzzle, a ‘conditionality’ view of intention has emerged: the contents of everyday intentions are claimed to be fraught with hidden conditional clauses. The paper argues that such claims are radically unmotivated: even unconditional intentions have only limited inferential import and hence contrast sharply with a ‘no matter what’ stance. The point is established by examining relevant patterns of reasoning from unconditional to conditional intentions. (shrink)

Translation of Aristotle's Physics I-II into Portuguese, with commentaries. Tradução para o português dos livros I e II da Física de Aristóteles, com comentários.

In this paper, we develop an impure somatic theory of emotion, according to which emotions are constituted by the integration of bodily perceptions with representations of external objects, events, or states of affairs. We put forward our theory by contrasting it with Prinz's pure somatic theory, according to which emotions are entirely constituted by bodily perceptions. After illustrating Prinz's theory and discussing the evidence in its favor, we show that it is beset by serious problems—i.e., it gets the neural correlates (...) of emotion wrong, it isn't able to distinguish emotions from bodily perceptions that aren't emotions, it cannot account for emotions being directed towards particular objects, and it mischaracterizes emotion phenomenology. We argue that our theory accounts for the empirical evidence considered by Prinz and solves the problems faced by his theory. In particular, we maintain that our theory gives a unified and principled account of the relation between emotions and bodily perceptions, the intentionality of emotions, and emotion phenomenology.

This is an introductory handbook for some of the main themes around the notion of predication in Aristotle. It does not aim at being exhaustive, but only sketches some important lines about the subject; it contains an introductory essay, besides the translation (into Portuguese) and commentary of basic texts (such as Posterior Analytics I-22, Categories 1-5, Interpretation 1-6 etc.).

This article gives a short presentation of reflexive imperativism, the intentionalist theory of valence I developed with Max Khan Hayward. The theory says that mental states have valence in virtue of having reflexive imperative content. More precisely, mental states have positive valence (i.e., feel good) in virtue of issuing the command "More of me!", and they have negative valence (i.e., feel bad) in virtue of issuing the command "Less of me!" The article summarises the main arguments in favour of reflexive (...) imperativism and against other intentionalist treatments of valence. (shrink)

This book discusses Aristotle’s notions of essence and substance as they are developed in Metaphysics ZH. I examine Aristotle's argument at length and defends an unorthodox interpretation according to which his motivation is to provide an answer against a conflation between criteria for existential priority (delivering substances as primary beings) and criteria for explanatory priority (delivering essences as primary principles).

ABSTRACT (ITA) Un’idea emerge, si sviluppa, guadagna consenso, muta, talvolta scompare per poi risorgere. Questo è anche stato il destino dell’idea di evoluzione, il cui lungo cammino viene ricostruito in questo saggio, dai Greci fino ai nostri giorni. A partire dal diciassettesimo secolo questa nozione assume sempre più rilevanza nello studio della natura. In ciascun pensatore l’idea di un’evoluzione delle specie viventi è stata accompagnata da una teoria volta a spiegare le cause e il meccanismo del mutamento. Questo saggio racconta (...) non soltanto la genesi e lo sviluppo dell’idea tout court che la natura in qualche modo si trasformi, ma anche la storia delle teorie che, assumendo come reale questa trasformazione, ne postulano una spiegazione. Particolare attenzione viene data ad alcuni aspetti spesso trascurati che hanno reso possibile il concetto di evoluzione del mondo vivente come la conosciamo adesso, di cui se ne mostra la rilevanza, già a partire dal pensiero greco. -/- ABSTRACT (ENG) An idea emerges, develops, gains consensus, evolves, sometimes disappears and then rises again. This was also the fate of the idea of evolution, whose long journey is reconstructed in this essay, from the Greeks to the present day. Since the seventeenth century, this idea has become more and more relevant in the study of nature. In each thinker the idea of an evolution of living species has been accompanied by a theory aimed at explaining the causes and the mechanism of change. This essay tells not only the genesis and development of the idea that nature somehow transforms itself, but also the history of the theories which, assuming this transformation as real, postulate an explanation. Particular emphasis is given to some often overlooked aspects that made possible the concept of evolution of the living world as we know it now, whose full relevance is shown, starting from Greek thought. Keywords: evolution, natural selection, Charles Darwin, history of ideas, history of science. (shrink)

In this paper, I present an interpretation of Wittgenstein's remarks on the experience of wonder at the existence of the world. According to this interpretation, Wittgenstein's feeling of wonder stems from perceiving the existence of the world as an absolute miracle, that is, as a fact that is in principle beyond explanation. Based on this analysis, I will suggest that Wittgenstein's experience is akin to what has been described by other authors such as Coleridge, Pessoa, Heidegger, Scheler, Sartre, and Hadot, (...) among many others. Through a comparison between Wittgenstein and Coleridge on the experience of existence, I shall highlight some core features of this experience, chief among them the use of the notion of nothingness in clarifying what is understood in the experience, the role of intuition, and the presence of a specific pathos. As a whole, this paper aims to provide a contribution to the project of a phenomenology of the experience of existence and intends to create a bridge for a dialogue between Wittgenstein and the phenomenological tradition on the enigma of existence.

In this chapter, I shall consider a number of connections between various ideas of the theory of styles of reasoning and the issue of the contingency and inevitability of science. By ‘contingency issue’ it is meant the question as to whether the history of a particular branch of our science could have taken a different route and provided results incompatible with those of our actual science. Apart from Hacking’s recent comments, the discussions on the contingency issue have not involved the (...) notion of style of reasoning. I will fill this gap in the literature by drawing some important implications for the issue of contingency from the theory of styles of reasoning that I have developed so far. I shall address four fundamental questions. First of all, in the next section I shall discuss to which extent the emergence of styles of reasoning at a certain point of history is a contingent circumstance. In the following section I shall ask whether the endurance of styles of reasoning was inevitable by tackling the connected question as to why the styles are long lasting. Afterwards, I shall focus on the growth of knowledge by dealing with questions such as: if a certain style of reasoning continues to be employed and if Q is a ‘live question’, is science bound to converge on a single answer to Q? Finally, on the basis of my previous reflections I shall look into the question of the convergence of science in the long run. The answers to these questions will rely on some basic assumptions of the theory of style of reasoning and imply a picture of the evolution of sciences in which both contingency and inevitability play a key role.

Translation of Aristotle's Parts of Animals Book I into Portuguese, with full commentaries.

Aristotle contrasts episteme and doxa through the key notions of universal and necessary. These notions have played a central role in Aristotle’s characterization of scientific knowledge in the previous chapters of APo. They are not spelled out in APo I.33, but work as a sort of reminder that packs an adequate characterization of scientific knowledge and thereby gives a highly specified context for Aristotle’s contrast between episteme and doxa. I will try to show that this context introduces a contrast in (...) terms of explanatory claims: on the one hand, episteme covers those claims which capture explanatory connections that are universal and necessary and thereby deliver scientific understanding; on the other hand, doxa covers the explanatory attempts that fail at doing so.

According to the perceptual view of language comprehension, listeners typically recover high-level linguistic properties such as utterance meaning without inferential work. The perceptual view is subject to the Objection from Context: since utterance meaning is massively context-sensitive, and context-sensitivity requires cognitive inference, the perceptual view is false. In recent work, Berit Brogaard provides a challenging reply to this objection. She argues that in language comprehension context-sensitivity is typically exercised not through inferences, but rather through top-down perceptual modulations or perceptual learning. (...) This paper provides a complete formulation of the Objection from Context and evaluates Brogaards reply to it. Drawing on conceptual considerations and empirical examples, we argue that the exercise of context-sensitivity in language comprehension does, in fact, typically involve inference. (shrink)

This chapter has two main sections. In the first section I briefly sketch Immanuel Kant’s moral theory as laid out in his Groundwork of the Metaphysics of Morals (1785). I explain Kant’s claim that morality must be grounded on what he calls a categorical imperative and examine his three formulations of this categorical imperative. In the second section I explain the distinction between “deontological” and “teleological” ethical theories. Kantian ethics is often presented as the paradigm example of a deontological ethical (...) theory, but I question whether Kant’s ethics should be understood as purely deontological. (shrink)

This paper discusses some issues concerning the definition of moral virtue in Nicomachean Ethics 1106b 36- 1107a 2. It is reasonable to expect from a definition the complete enumeration of the relevant features of its definiendum, but the definition of moral virtue seems to fail in doing this task. One might be tempted to infer that this definition is intended by Aristotle as a mere preliminary account that should be replaced by a more precise one. The context of the argument (...) Aristotle develops in Book II of his NE give us some help. I argue that the definition of moral virtue, once considered in the light of its context, is far from being an incomplete and provisional account: it rather introduces coherently the same notion of moral virtue that Aristotle employs in other texts (as in Nicomachean Ethics VI 13). My main proposal is that the way in which "hexis" is understood in the context of previous chapters allows Aristotle to encode in it the notion of an ability to do the right things regularly. Thus, moral virtue is a "hexis prohairetike etc.", but the ability to do the right things regularly is already encoded in the occurrence of "hexis" in the definiens account of moral virtue, as if Aristotle meant "hexis [praktike] prohairetike".

We present epistemic multilateral logic, a general logical framework for reasoning involving epistemic modality. Standard bilateral systems use propositional formulae marked with signs for assertion and rejection. Epistemic multilateral logic extends standard bilateral systems with a sign for the speech act of weak assertion (Incurvati and Schlöder 2019) and an operator for epistemic modality. We prove that epistemic multilateral logic is sound and complete with respect to the modal logic S5 modulo an appropriate translation. The logical framework developed provides the (...) basis for a novel, proof-theoretic approach to the study of epistemic modality. To demonstrate the fruitfulness of the approach, we show how the framework allows us to reconcile classical logic with the contradictoriness of so-called Yalcin sentences and to distinguish between various inference patterns on the basis of the epistemic properties they preserve.

I review recent work on Phenomenal Conservatism, the position introduced by Michael Huemer according to which if it seems that P to a subject S, in the absence of defeaters S has thereby some degree of justification for believing P.

My aim is to examine Aristotle's hylomorphism as a model for scientific explanation of living beings. I argue that the issue of matter-form relation should be connected with the opposition between the necessity of material and efficient causes and the teleology of forms. Form (as "telos") is a principle able to organize the appropriate conjunction of material and efficient causes. Formal and final causes are not a trick for filling the "gap in causation", nor are they bare heuristic tools for (...) inquiring into the "true" causes. The primacy of formal and final causes guarantees an appropriate account of material and efficient causes inasmuch as form and "telos" are responsible for bending and organizing the original dispositions of the material elements.

This chapter argues in favour of three interrelated points. First, I argue that demonstration (as expression of scientific knowledge) is fundamentally defined as knowledge of the appropriate cause for a given explanandum: to have scientific knowledge of the explanandum is to explain it through its fully appropriate cause. Secondly, I stress that Aristotle’s notion of cause has a “triadic” structure, which fundamentally depends on the predicative formulation (or “regimentation”) of the explanandum. Thirdly, I argue that what has motivated Aristotle to (...) choose the syllogism as a demonstrative tool was precisely the fact that syllogisms are apt to express causal relations in their triadic structure. Instead of complaining against Aristotle’s preference for the syllogisms as demonstrative tools, I argue that Aristotle was fully aware of the advantages of regimenting the explanandum into a predication. One of these advantages is to abandon a purely extensional standpoint and to highlight the importance of the notion of relevancy in explanation. (shrink)

I discuss in this paper the six requirements Aristotle advances at Posterior Analytics A-2, 71b20-33, for the premisses of a scientific demonstration. I argue that the six requirements give no support for an intepretation in terms of “axiomatization”. Quite on the contrary, the six requirements can be consistently understood in a very different picture, according to which the most basic feature of a scientific demonstration is to explain a given proposition by its appropriate cause.

In Prior Analytics I.30, Aristotle seems too much optmistic about finding out the principles of sciences. For he seems to say that, if our empirical collection of facts in a given domain is exhaustive or sufficient, it will be easy for us to find out the explanatory principles in the domain. However, there is a distance between collecting facts and finding out the explanatory principles in a given domain. In this paper, I discuss how the key expression in the sentence (...) at 46a25 should be interpreted: “the true characteristics of things” (“τῶν ἀληθῶς ὑπαρχόντων τοῖς πράγμασιν”). I argue that, on a more accurate interpretation of the expression, Aristotle’s point would cease to look like a piece of naïve or even silly optimism. (shrink)
