I Think. Therefore I'm Tired. — Funny René Descartes Coffee Mug

He invented modern philosophy. He invented analytic geometry. He laid the groundwork for the scientific method. He also famously refused to get out of bed before noon, and died at age 53 because Queen Christina of Sweden made him take 5am meetings.

This 11oz ceramic mug features René Descartes in his off-hours uniform — cardigan, loafers, hair untouched, quill at the ready — the father of modern thought finally admitting what his entire life implied: I Think. Therefore I'm Tired. The two are connected.

Drink your coffee. Doubt everything. Survive your Monday.

Part of the Off-Duty Philosophers Collection — where history's greatest thinkers finally admit they were just winging it.
