In his 1896 lecture course on logic–reportedly a blueprint for the Prolegomena to Pure Logic –Husserl develops an explicit account of logic as an independent and purely theoretical discipline. According to Husserl, such a theory is needed for the foundations of logic (in a more general sense) to avoid psychologism in logic. The present paper shows that Husserl’s conception of logic (in a strict sense) belongs to the algebra of logic tradition. Husserl’s conception is modeled after arithmetic, and respectively logical (...) inferences are viewed as analogical to arithmetical calculation. The paper ends with an examination of Husserl’s involvement with the key characters of the algebra of logic tradition. It is concluded that Ernst Schröder, but presumably also Hermann and Robert Grassmann influenced Husserl most in his turn away from psychologism. (shrink)

John Searle''s hypothesis of the Background seems to conflict with his initial representationalism according to which each Intentional state contains a particular content that determines its conditions of satisfaction. In Section I of this essay I expose Searle''s initial theory of Intentionality and relate it to Edmund Husserl''s earlier phenomenology. In Section II I make it clear that Searle''s introduction of the notion of Network, though indispensable, does not, by itself, force us to modify that initial theory. However, a comparison (...) of this notion to the notion of horizon from Husserl''s later phenomenology and an interpretation of Husserl''s conception of the determinable X as providing a solution to the problem of perceptual misidentification lead me to conclude that in his discussion of ''twin examples'' Searle had better modified his initial theory. Finally, I critically examine Searle''s claim that anyone who tries seriously to follow out the threads in the Network will eventually reach a bedrock of non-Intentional capacities. In Section III I show in detail, partly in a rather Husserlian vein, that Searle''s four official arguments for the Background thesis, though containing some very valuable contributions to a theory of linguistic skills, are not convincing at all if they are to be understood as going beyond the scope of Searle''s ''content-cum-Network'' picture of Intentionality. The upshot of these considerations is that the Background thesis should be read as a thesis concerning the causal neurophysiological preconditions of human Intentionality rather than concerning the logical properties of Intentional states in general. Recently Searle himself has come to the same result, but he does not say for which reasons. The present essay makes it clear why Searle just had to arrive at this important result. (shrink)

In Section 1, the author argues that Bolzano does not have a Meinongian view of merely possible objects, not even in the context of his theory of intentionality. In section 2, it is argued that Williamson’s necessitist conception, according to which there is a merely possible golden mountain, was not anticipated by Bolzano. An eternalist reconstruction is rejected as well. The argument takes recourse to Bolzano’s semantics of temporal statements, which also underlies his argument for the eternity of substances and (...) makes it plausible to assume that Bolzano had a perdurantist view, according to which there are merely possible objects just in case there are actual objects whose generation is to be metaphysically explained, in terms of grounding, by recourse to a merely possible object’s being replaced by an actual object. Furthermore, it is argued that merely possible objects à la Bolzano are not substances, in his narrow sense of the term, and that his case for such objects in connection with his view of generation is less than convincing. However, section 3 argues that Bolzano’s conception combines with his view of substance to yield an interesting perdurantist conception of personal identity. (shrink)

El artículo aborda ciertos pasajes fundamentales de la Wissenschaftslehre de Bolzano, analizando algunos de sus conceptos claves tales como los de «proposición en sí» o «representación en sí». Haciendo especial hincapié en el estatus ontológico peculiar de estas «entidades en sí» que presenta Bolzano, mostraremos que su obra desarrolla una auténtica teoría semántica de la dimensión del sentido y de lo pensable, que no sólo no depende de la ontología, sino que desborda a la misma.

Some Austro-German philosophers considered thoughts to be mind-dependent entities, that is, psychic products. Yet these authors also attrib- uted “objectivity” to thoughts: distinct thinking subjects can have mental acts with “qualitatively” the same content. Moreover, thoughts, once built, can exist beyond the life of their inventor, “embodied” in “documents”. At the beginning of the 20th century, the notion of “psychic product” was at the centre of the debates on psychologism; a hundred years later, it is rather at the margins of (...) the history of philosophy. While Twardowski’s theory of products has been fre- quently studied, those of Stumpf and the late Husserl have been much less dis- cussed. A presentation of the Austro-German debates about psychic products is all the more important since these discussions might be of direct interest for contemporary philosophy of mind and epistemology. This paper examines the Austro-German notion of psychic products in Stumpf, Twardowski, and the later Husserl. (shrink)

Through a detailed explication of Bernard Bolzano's semantics of natural kind terms, I elucidate why and to what extent he should be recognized as a remarkable anticipator of semantic externalism. Bolzano deals with kind terms in a brief sub-section of the first volume of his Theory of Science. He divides such terms into two sub-categories, roughly corresponding to organic and inorganic kinds. It is Bolzano's account of inorganic kind terms, such as ‘gold’, that confers on him the status of an (...) anticipator of semantic externalism. He argues that ‘gold’ may be used in a way such that the superficial attributes that language users associate with it merely serve to enable them to recognize its instances. They do not, however, constitute the idea designated by the term nor do they determine its extension. Instead, the term designates an idea representing gold's unknown inner attributes, which are causally responsible for its superficial attributes. (shrink)

Dass Husserl auch im Hundert-Jahres-Jubiläum der Ideen I tatsächlich „aktuell“ und für eine Reihe gegenwärtiger philosophischer Trends höchst anschlussfähig ist, das verspricht nicht nur der Titel, dies belegen auch eindrücklich die zwölf Aufsätze des vorliegenden Bandes. Das Buch stellt nicht nur eine hervorragende Ergänzung zu dem thematisch stärker fokussierten rezenten Sammelband Husserl und die Philosophie des Geistes (Frank and Weidtmann 2010) dar, zumal auch hier der Anti- bzw. Non-Naturalismus Husserls einen der Leitfäden des Buches bildet; insgesamt handelt es sich dabei (...) in Breite und Tiefe, aber auch was die Qualität der Mehrzahl der Beiträge betrifft, vielmehr um eines der gelungensten der neueren, und nicht nur der deutschsprachigen, Kompendien zu Husserl (vgl. etwa Ierna et al. 2010; Centrone 2013; Embree and Nenon 2013).Entlang einer klugen editorischen Organisation fügen sich die Beiträge gut in die drei Teile Ontologie, Sprachphilosophie & Philosophie des Geistes und Ha.

The article addresses the works of three 19th-century philosophers: Herbart, Bolzano and Lotze. Despite their differences, i will analyze two essential features they share: their refusal to psychologism as the radicalization of psychology as the ultimate source of philosophy , and the positing of an ideal ‘reality’, independent from both sensibility and the mental and linguistic dimensions, upon which the refusal to psychologism is founded . As a conclusion, i will show how, according to these authors, this platonic, ideal background (...) constitutes the very foundation of every meaningful thought. (shrink)
