In _Kazimierz Twardowski: A Grammar for Philosophy_ Maria van der Schaar shows the importance of Twardowski’s method, his philosophical grammar, for both the Lvov-Warsaw School, and analytic philosophy today.

In view of rapid and dramatic technological change, it is important to take the special requirements of privacy protection into account early on, because new technological systems often contain hidden dangers which are very difficult to overcome after the basic design has been worked out. So it makes all the more sense to identify and examine possible data protection problems when designing new technology and to incorporate privacy protection into the overall design, instead of having to come up with laborious (...) and time-consuming “patches” later on. This approach is known as “_Privacy by Design_” (PbD). (shrink)

How is Frege able to claim that the notion of judgement is essential to his logic without introducing a form of psychologism? I argue first that Frege’s logical notion of judgement is to be distinguished from an empirical notion of judgement, that it cannot be understood as an abstract, idealized notion, and that there are doubts concerning a transcendental reading of Frege’s writings. Then, I explain that the logical notion of judgement has to be understood from a first-person perspective, to (...) be contrasted with a third-person perspective, in which judgement is understood as an empirical, psychological phenomenon. Frege’s logic is essentially a first-person engagement, as each of us can make use of the ideography as a science of logic only if we ourselves have made the relevant judgements. Finally, I claim that the judging agent as conceived by Frege can, after all, be understood as a transcendental ego. (shrink)

Activist, journalist, and theorist, Eqbal Ahmad was admired by and consulted by activists and policymakers. He inspired new ways of thinking about militant Islam, the U.S. involvement in Vietnam, and the Cold War. This intellectual biography relates Ahmad's life to the political transformations that occurred globally in the second half of the twentieth century"--Provided by publisher.

To understand pre-Fregean theories of judgment and proposition, such as those found in Locke and the Port-Royal logic, it is important to distinguish between propositions in the modern sense and propositions in the pre-Fregean sense. By making this distinction it becomes clear that these pre-Fregean theories cannot be meant to solve the propositional attitude problem. Notwithstanding this fact, Locke and Arnauld are able to make a distinction between asserted and unasserted propositions (in their sense). The way Locke makes this distinction (...) turns out to be very different from the way it is made by Arnauld. (shrink)

Taking Per Martin-Löf’s constructive type theory as a starting-point a theory of assertion is developed, which is able to account for the epistemic aspects of the speech act of assertion, and in which it is shown that assertion is not a wide genus. From a constructivist point of view, one is entitled to assert, for example, that a proposition A is true, only if one has constructed a proof object a for A in an act of demonstration. One thereby has (...) grounded the assertion by an act of demonstration, and a grounding account of assertion therefore suits constructive type theory. Because the act of demonstration in which such a proof object is constructed results in knowledge that A is true, the constructivist account of assertion has to ward off some of the criticism directed against knowledge accounts of assertion. It is especially the internal relation between a judgement being grounded and its being known that makes it possible to do so. The grounding account of assertion can be considered as a justification account of assertion, but it also differs from justification accounts recently proposed, namely in the treatment of selfless assertions, that is, assertions which are grounded, but are not accompanied by belief.

In several manuscripts, written between 1894 and 1897, Twardowski developed a new theory of judgement with two types of judgement: existential and relational judgements. In Zur Lehre he tried to stay within a Brentanian framework, although he introduced the distinction between content and object in the theory of judgement. The introduction of this distinction forced Twardowski to revise further Brentano'stheory.His changes concerned judgements about relations and about non-present objects. The latter are considered special cases of relational judgements. The existential judgements (...) are analysed in a Brentanian way; whereas relational judgements are analysed in a Brentanian way only as far as the act is concerned, but not when it comes to the object: the object of a relational judgement is a relationship. With this notion of relationship Twardowski comes close to introducing a concept of state of affairs for the object of (relational) judgements. (shrink)

In this paper it will be argued that Brentano's later writings about this topic can be understood better if one describes it as a result partly of his immanent development and partly of Brentano's reactions to his contemporaries.

The notion of cognitive act is of importance for an epistemology that is apt for constructive type theory, and for epistemology in general. Instead of taking knowledge attributions as the primary use of the verb 'to know' that needs to be given an account of, and understanding a first-person knowledge claim as a special case of knowledge attribution, the account of knowledge that is given here understands first-person knowledge claims as the primary use of the verb 'to know'. This means (...) that a cognitive act is an act that counts as cognitive from a first-person point of view. The method of linguistic phenomenology is used to explain or elucidate our epistemic notions. One of the advantages of the theory is that an answer can be given to some of the problems in modern epistemology, such as the Gettier problem. (shrink)

The meaning of a declarative sentence and that of an interrogative sentence differ in their aspect of mood. A semantics of mood has to account for the differences in meaning between these sentences, and it also has to explain that sentences in different moods may have a common core. The meaning of the declarative mood is to be explained not in terms of actual force (contra Dummett), but in terms of potential force. The meaning of the declarative sentence (including its (...) mood) is called the assertion-candidate, which is explained by what one must know in order to be entitled to utter the declarative with assertive force. Both a cognitive notion (knowledge) and a pragmatic notion (assertive force) are thus part of the explanation of the assertion-candidate. Davidson’s criticism that such a theory is in need of an account of the distinction between standard and non-standard uses of the declarative is answered: without counter-indications an utterance of a declarative sentence is understood as having assertive force. The meaning of an interrogative sentence, the question-candidate, and that of the other sentence types can ultimately be explained in terms of their specific relations to the assertion-candidate. Martin-Löf’s constructive type theory is used to show the philosophical relevance of a semantics of mood. The constructivist notion of proposition needs to be embedded in a theory of the assertion-candidate, which fulfils the offices of being the meaning of the declarative sentence, the content of judgement and assertion and the bearer of epistemic truth.

There are two notions of intentionality: the first contains the thesis that our acts of thinking, judging and loving have a content; the second that our mental acts are about something external to the act. Brentano uses the term ‘intentionality’ only in relation to the first notion; for him, intentionality does not function as a bridge between the mind and the external world. Is it possible for a phenomenologist like Brentano to give an account of the second notion of intentionality? (...) It is argued that this is possible, but not without introducing the notion of judgement. A comparison with Mill’s distinction between connotation and denotation, and with Frege’s distinction between sense and reference shows how original Brentano’s theory is. (shrink)

This compelling reevaluation of the relationship between logic and knowledge affirms the key role that the notion of judgement must play in such a review. The commentary repatriates the concept of judgement in the discussion, banished in recent times by the logical positivism of Wittgenstein, Hilbert and Schlick, and the Platonism of Bolzano. The volume commences with the insights of Swedish philosopher Per Martin-Löf, the father of constructive type theory, for whom logic is a demonstrative science in which judgement is (...) a settled feature of the landscape. His paper opens the first of four sections that examine, in turn, historical philosophical assessments of judgement and reason; their place in early modern philosophy; the notion of judgement and logical theory in Wolff, Kant and Neo-Kantians like Windelband; their development in the Husserlian phenomenological paradigm; and the work of Bolzano, Russell and Frege. The papers, whose authors include Per Martin-Löf, Göran Sundholm, Michael Della Rocca and Robin Rollinger, represent a finely judged editorial selection highlighting work on philosophers exercised by the question of whether or not an epistemic notion of judgement has a role to play in logic. The volume will be of profound interest to students and academicians for its application of historical developments in philosophy to the solution of vexatious contemporary issues in the foundation of logic. ​.

With the publication of Locke’s early manuscripts on toleration and the drafts for the Essay, it is possible to understand to what extent Locke’s ideas on religious toleration have developed. Although the important arguments for toleration can already be found in these early texts, Locke was confronted with a problem in his defence of toleration that he needed to solve. If faith, as a form of judgement, is involuntary, as Locke claims, how can one be held accountable for the faith (...) one has? In answer to this question reason comes to play a more prominent role in Locke’s notion of faith and in his defence of religious toleration, and in his philosophy in general. This notion of reason is not the reason we use for mathematical demonstrations. It is rather reason as we use it in discussion, and is thus fallible. It is precisely this kind of reason that played a central role in the Remonstrant religion to which Locke was closely connected at the time he developed a new argument for religious toleration when he was in the Netherlands.

In this paper I argue for the thesis that Stout's category of abstract particulars (what Husserl calls "moments') has played a role in the transition from Bradleian idealism to British analytic philosophy. That category plays this role as part of a new theory of wholes, parts and relations that Stout develops in opposition to Bradley. In Stout's theory abstract particulars are dependent parts of wholes. The critical remarks that G. E. Moore and Kevin Mulligan have made concerning Stout's identification of (...) abstract particulars and predicates are elaborated in this paper. Notwithstanding the fact that Stout mistakenly identifies abstract particulars with predicates, the category of abstract particulars may be of value in a theory of individuals, universals and truthmakers.

Introduction to the special issue including papers about Susan Stebbing, Susanne Langer and Maria Kokoszyńska.

The central question of my paper is whether there is a coherent logical theory in which truth is construed in epistemic terms and in which also some version of the law of excluded middle is defended. Brentano in his later writings has such a theory.2 My first question is whether his theory is consistent. I also make a comparison between Brentano’s view and that of an intuitionist at the present day, namely Per Martin-Löf. Such a comparison might provide some insight (...) into what is essential to a theory that understands truth in epistemic terms. (shrink)

Aristotelian ideas on analogy that may be found in Brentano's early thesis help to elucidate his theory of truth, especially what Brentano wrote on truth at the end of his life. It seems as though Brentano did not distinguish between the notion of truth and the notion of evidence ; but, in fact, he has two notions of truth. The original sense of truth in a true judgment means evidence ; in a derived or analogical sense, a blind judgment, which (...) corresponds to an evident judgment in all other aspects, is also called true. Such a judgment is true in so far as it may be judged with evidence. (shrink)

The first half of the paper gives an interpretation of Locke's concept of knowledge, which shows that Aristotelian ideas and later scholasticism has had some influence on Locke's Essay Concerning Human Understanding. The second half of the paper shows the uniqueness of Locke's account of knowledge by contrasting it with the standard account of knowledge as justified true belief. The most important point is that knowledge, for Locke, is primarily an act, not a state.
