Frase de David Hume

“Reason is, and ought only to be the slave of the passions, and can never pretend to any other office than to serve and obey them.”

“Every idea is a copy of a preceding impression.”

“A wise man [...] proportions his belief to the evidence.”

“Be a philosopher; but, amidst all your philosophy, be still a man.”

“The greater part of mankind is divided into two groups: those who do not think, and those who think wrongly.”
