This book deals with an internal theme of metaphysics, which is the metaphysics of the laws of nature. The author presents traditional contemporary theories, as well as his own original theory, and evaluates each one at a time. He also addresses the problem of the modality of the laws of nature and makes some criticism of the standard view of necessity as truth in all possible worlds, and shows an application of his discussion to the metaphysics of physics. / Este (...) livro trata de um tema interno à metafísica, que é a metafísica das leis da natureza. O autor apresenta as teorias tradicionais contemporâneas, tal como também a sua própria teoria original, e avalia cada uma delas por vez. Ele também aborda o problema da modalidade das leis da natureza e apresenta uma certa crítica à visão padrão da necessidade como verdade em todos os mundos possíveis, e mostra uma aplicação da sua discussão à metafísica da Física.

It is widely accepted that if a property is essential then it is necessary. Against this I present numerous counterexamples from biology and chemistry, which fall into two groups: (I) A property is essential to a genus or species, yet some instances of this genus or species do not have this essential property. (II) A property is essential to a genus, yet some species of this genus do not have this essential property. I discuss and reject four minor objections. Then (...) I discuss in depth whether a distinction between constitutive essence and consequential essence is able to handle these counterexamples. I conclude that this distinction is better put as one between (1) the essence, which is necessary, and (2) the essential properties, which are not formally necessary. An essence of an object X is the substantial universal expressed by its real definition. An object X has a property P essentially iff the property P is explanatory and non-trivial, and P follows from the essence of X. (shrink)

In this paper we explicate the notion of a miracle and highlight a suitable ontological framework for it. Our proposal draws on insights from Aquinas’s discussion of miracles and from the modern ontology of powers. We argue that each substance possesses a characteristic set of natural powers and dispositions which are operative or become manifest in the right circumstances. In a miracle divine intervention activates the fundamental disposition inherent in each creature to be responsive to God’s call. Thus, a miracle (...) brings something about which a substance’s set of natural powers and dispositions could not bring about by itself. (shrink)

Miracles are commonly understood in the way David Hume defined them: as violations of the laws of nature. I argue, however, that the conjunction of Hume’s definition with a neo-Humean view of the laws of nature yields objectionable consequences. In particular, the two jointly imply that some miracles are logically impossible. A better way of thinking about miracles, I suggest, is on a neo-Aristotelian metaphysics. On that view, the laws of nature contain built-in ceteris paribus clauses that allow for the (...) possibility of external influences in the natural world. Miracles, understood as instances of external, divine influence, would therefore neither violate the laws of nature nor be instances of those laws. In this respect, neo-Aristotelians have an advantage over neo-Humeans in providing a coherent account of miracles. (shrink)

The goal of this thesis to defend the philosophical view of the new ante rem substantivism against its supposed alternatives. To achieve such goal, we will present four views about the nature of laws, two kinds of realism and two kinds of anti-realism, and evaluate them critically. The disadvantages from those theories are going to be presented for us to show that they are insufficient to provide a metaphysics that is able to explain the world's counterfactuality, universality, and regularity, and (...) that just one form of realism, the new ante rem substantivism, can. This goal is important because the concept of laws of nature is widely used in many areas of science and philosophy, and because according to the view we accept, the laws may fulfill some theoretical roles, and not others. We intent to show that the new ante rem substantivism's laws are able to fulfill the roles that scientists would hope the natural laws to fulfill. (shrink)

Anyone who tries to understand categories soon runs into the problem of giving an account of the unity of a category. Call this the “unity problem.” In this essay, I describe a distinctive and under-studied version of the unity problem and discuss how it might be solved. First, I describe various versions of the unity problem. Second, I focus on one version and argue that it is best dealt with by thinking of at least some categories as “norm-constituted,” in a (...) sense that I try to make clear. Third, I discuss some objections to my proposal. Fourth, I compare norm -constituted categories to categories that are normative in a different sense. Fifth, I briefly discuss the possibility of grounding the normativity of norm-constituted categories. Finally, I raise a few questions for further research. (shrink)

Moral principles play important roles in diverse areas of moral thought, practice, and theory. Many who think of themselves as ‘moral generalists’ believe that moral principles can play these roles—that they are capable of doing so. Moral generalism maintains that moral principles can and do play these roles because true moral principles are statements of general moral fact (i.e. statements of facts about the moral attributes of kinds of actions, kinds of states of affairs, etc.) and because general moral facts (...) explain particular moral facts (i.e. facts about the moral attributes of particulars). Moral holism maintains that what is a moral reason to φ in one case may not be one in another, and may even be a moral reason not to φ given suitable circumstances. Some ‘moral particularists’ maintain that moral holism motivates scepticism about the existence of and need for moral principles, along with scepticism about the viability of principle-based approaches to ethics and moral theory. But I argue that moral holism is itself a form of moral generalism, one that takes facts about the right- and wrong-making powers of (generic) moral factors to explain certain particular moral facts—namely, the rightness and wrongness of particular actions. I also argue that a moral-theoretic version of dispositionalism—the view that dispositions, powers, or capacities are the fundamental units of explanation—explains both why moral holism is true and why moral generalism is true.

The claim that a miracle is a violation of a law of nature has sometimes been used as part of an a priori argument against the possibility of miracle, on the grounds that a violation is conceptually impossible. I criticize these accounts but also suggest that alternative accounts, when phrased in terms of laws of nature, fail to provide adequate conceptual space for miracles. It is not clear what a ???violation??? of a law of nature might be, but this is (...) not relevant to the question of miracles. In practice, accounts of miracle tend to be phrased in terms of God's act not in terms of laws of nature. Finally, I suggest that the a priori argument reflects an intellectual commitment that is widely held, though wrongly built into the argument itself. (shrink)

[full article, abstract in English; only abstract in Lithuanian] This article presents the results of a broader research project which aims to argue for the normativity of scientific laws. Usually scientific laws are regarded as descriptive, which contrasts them to prescriptive norms. To show their normativity, I utilize the logical account of explicitly normative systems by Carlos Alchourrón and Eugenio Bulygin. I identify the characteristic elements of normativity and analyse accounts of implicit normativity in science using those terms to show (...) the affinities of explicit and implicit normativities. The research project continues with the substantiation of the normativity of scientific laws in detail and the results will be presented in Normativity of Scientific Laws. (shrink)

The purpose of this paper is to present a philosophical worldview, specifically metaphysical. This is important precisely to obtain a generalist view of reality, at a time when philosophical discussions are becoming increasingly specialized. The metaphysical worldview presented here is a general perspective on time, space, matter, laws of nature, the mind and the normativity. In order to achieve such goal, (1) we will talk about the nature of philosophy and its relation to the construction of a worldview, (2) we (...) will discuss some arguments to talk about the nature of the aforementioned entities, and (3) we will conclude by presenting a unified metaphysical worldview that takes these arguments into account.

I question here the differentiation of kinds as substantive universals in Lowe and Ellis’ metaphysics, by taking up, for the argument’s sake, two extreme approaches on kind differentiation and kind change, a Heraclitan and a Spinozan approach. I show that, as things currently stand, Heraclitanism or Spinozism about kinds is consistent with the broad tenets of Lowe and Ellis’ metaphysics of kinds.
