6. Immanuel Kant
As one of the greatest philosophers of the 18th century, you might think that Immanuel Kant enjoyed living life as much as studying it. However, this genius was kind of a Grinch when it came to women, friends or pretty much anything that seemed fun.
Immanuel Kant didn’t listen to music, didn’t associate with other philosophers and rarely got along with people. Consequently, he’s never been in a relationship and most likely died a virgin.
