Hans Vaihinger

Hans Vaihinger (September 25, 1852 – December 18, 1933) was a German philosopher, best known as a Kant scholar and for his Philosophie des Als Ob (Philosophy of As If), published in 1911, but written more than thirty years earlier.

Vaihinger was born in Nehren, Württemberg, Germany, near Tübingen, and raised in what he himself described as a "very religious milieu". He was educated at Tübingen, Leipzig, and Berlin, became a tutor and later a philosophy professor at Strasbourg before moving to the university at Halle in 1884. From 1892, he was a full professor.
