quote of the day

"There is no novelty to me in the reflection that, from my earliest years, I have accepted many false opinions as true, and that what I have concluded from such badly assured premises could not but be highly doubtful and uncertain. From the time that I first recognized this fact, I have realized that if I wished to have any firm and constant knowledge in the sciences, I would have to undertake, once and for all, to set aside all the opinions which I had previously accepted among my beliefs and start again from the very beginning."

-- Descartes, from the First Meditation
