Frege and Hume at Thanksgiving

October 2, 2018 by

0

It’s almost Thanksgiving here in Canada, so here’s a thanksgiving themed post about concepts from Frege and Neo-logicism. In his Grundlagen (1884), Frege proposes that the number that belongs to two concepts is the same just in case the objects falling under those concepts can be correlated one-to-one (i.e. they’re equinumerous). The formalization of that claim is […]

It’s a Small World: The Leśniewski-Sobociński Theorem.

The other day I was reading M. Resnik’s Frege and the Philosophy of Mathematics (1980).

This intrigued me, as […]

Their talk of cognitive dissonance and the metaphor of the ‘pyramid of choice’ has inspired my comments below. Although the ideas in this book have obvious ramifications for psychology, psychotherapy, political science, […]

Disclaimer: I should state, first and foremost, that though I am a student in the philosophy department at the University of Calgary, my opinions in no way represent or reflect those of my peers and supervisors.

Here’s W. V. O. Quine discussing the fact that Frege didn’t adopt a type theoretic approach (like Russell and Whitehead’s) when faced with Russell’s paradox. Actually, it is not to be wondered that Frege did not think of this course, or, thinking of it, adopt it. It was by having all his classes at ground […]
