Meditation I — Of Things Doubtful

Some years past I perceived how many Falsities I admitted as Truths in my Younger years, and how Dubious those things were which I raised from thence; and therefore I thought it requisite (if I had a designe to establish any thing that should prove firme and permanent in sciences) that once in my life I should clearly cast aside all my former opinions, and begin a new from some First principles. But this seemed a great Task, and I still expected that maturity of years, then which none could be more apt to receive Learning; upon which Account I waited so long, that at last I should deservedly be blamed had I spent that time in Deliberation which remain’d only for Action.

This day therefore I conveniently released my mind from all cares, I procured to my self a Time Quiet, and free from all Business, I retired my self Alone; and now at length will I freely and seriously apply my self to the General overthrow of all my former Opinions.
