Christine Ladd-Franklin is often hailed as a guiding star in the history of women logic—not only did she study under C. S. Peirce and was one first to receive PhD from Johns Hopkins, also, according many modern commentators, solved logical problem which had plagued field syllogisms since Aristotle. In this paper, we revisit claim, posing answering two distinct questions: Which solve her thesis,...

Na era da pós-verdade que atravessamos, nunca foi tão premente discutir o valor verdade. Este artigo tem por objetivo colocar em relevo estatuto metafísico verdade na obra de C. S. Peirce a partir sua raiz no falibilismo definido como doutrina nosso conhecimento é absoluto, mas sempre navega, assim dizer, um continuum incerteza e indeterminação. Entretanto, entendimento falibilista pressupõe se...

We present a two-sorted algebra, called a Peirce algebra, of relations and sets interacting with each other. In a Peirce algebra, sets can combine with each other as in a Boolean algebra, relations can combine with each other as in a relation algebra, and in addition we have both a relationforming operator on sets (the Peirce product of Boolean modules) and a set-forming operator on relations (...

This article focuses on Edmund Husserl’s first and most enduring interaction with pragmatism, the conception of habit. began a decade before writings phenomenology, continued throughout time he invented developed his new phenomenological method. Husserl encountered pragmatic habit from founder pragmatism Charles S. Peirce around 1890. then further interacted theory through work William James Jo...

Debates concerning the character, scope, and warrant of abductive inference have been active since Peirce first proposed that there was a third form of inference, distinct from induction and deduction. Abductive reasoning has been dubbed weak, incoherent, and even nonexistent. Part, at least, of the problem of articulating a clear sense of abductive inference is due to difficulty in interpretin...

Peirce (2007) proposed a two-stage conjunction detection model in which the outputs of first-stage neurons selective for the conjunction components were summed to give the conjunction-detector output. He argued that a saturating (monotonic) or supersaturating (nonmonotonic) nonlinearity on the outputs of the first-stage neurons made this detector more selective for conjunctions by increasing th...

Cet article voudrait aborder la question du deepfake d’information en le positionnant face aux exigences de sémiotique pragmatique américaine. Signe d’évidence, croyance fondamentale (urdoxa) visage soumis au joue avec réel, vérité et croyance. Il semble important pour chercheur poser les limites ces concepts éprouver à ce défi d’« efficace signe » qu’est deepfake. En effet, propédeutique théor...
