Conquer Yourself Rather Than The World.

Hence Reason Also Demands That, Since Our Thoughts Cannot All Be True Because We Are Not Wholly Perfect, What Truth They Do Possess Must Inevitably Be Found In The Thoughts We Have When Awake, Rather Than In Our Dreams.

When I Consider This Carefully, I Find Not A Single Property Which With Certainty Separates The Waking State From The Dream. How Can You Be Certain That Your Whole Life Is Not A Dream?

If I Go For The Alternative Which Is False, Then Obviously I Shall Be In Error; If I Take The Other Side, Then It Is By... Chance That I Arrive At The Truth, And I Shall Still Be At Fault.... In This Incorrect Use Of Free Will May Be Found The Privation Which Constitutes The Essence Of Error.

Although My Knowledge Grows More And More, Nevertheless I Do Not For That Reason Believe That It Can Ever Be Actually Infinite, Since It Can Never Reach A Point So High That It Will Be Unable To Attain Any Greater Increase.
