'Treatise of Human Nature' by David Hume
David Hume was an 18th-century Scottish philosopher who believed that everything we think we know is really just a matter of probability. He argued that reason doesn't motivate people. Which raises all sorts of questions, such as "So what's motivating you to write this?"
"The chief benefit, which results from philosophy, arises in an indirect manner, and proceeds more from its secret, insensible influence, than from its immediate application," Hume wrote, apparently responding to the aforementioned question.
