George Herbert Mead (1863—1931) George Herbert Mead is a major figure in the history of American philosophy, one of the founders of Pragmatism along with Peirce, James, Tufts, and Dewey. He published numerous papers during his lifetime and, following his death, several of his students produced four books in his name from Mead’s unpublished (and even unfinished) notes and manuscripts, from students’ notes, and from

Universals Universals are a class of mind-independent entities, usually contrasted with individuals (or so-called “particulars”), postulated to ground and explain relations of qualitative identity and resemblance among individuals.

Wittgenstein: Epistemology Although Ludwig Wittgenstein is generally more known for his works on logic and on the nature of language, but throughout his philosophical journey he reflected extensively also on epistemic notions such as knowledge, belief, doubt, and certainty.

Pseudoscience and the Demarcation Problem The demarcation problem in philosophy of science refers to the question of how to meaningfully and reliably separate science from pseudoscience. Both the terms “science” and “pseudoscience” are notoriously difficult to define precisely, except in terms of family resemblance. The demarcation problem has a long history, tracing back at the least to a speech given by Socrates in Plato’s Charmides,

Ninon de Lenclos (1620—1705) A salonnière during the reign of Louis XIV, Ninon de Lenclos embodied libertinism in both theory and practice.  As a notorious courtesan, Lenclos scandalized France by her numerous affairs with prominent statesmen and ecclesiastics.  As a philosopher, she justified sexual license by her naturalistic theories of human nature and of morality.  In Lenclos’s perspective, the human person is demonstrably a part of material
