Travelling Is Almost Like Talking

The Only Secure Knowledge Is That I Exist.

To Live Without Philosophizing Is In Truth The Same As Keeping The Eyes Closed Without Attempting To Open Them.

Give Me Extension And Motion And I Will Construct The Universe.

But I Cannot Forget That, At Other Times I Have Been Deceived In Sleep By Similar Illusions; And, Attentively Considering Those Cases, I Perceive So Clearly That There Exist No Certain Marks By Which The State Of Waking Can Ever Be Distinguished From Sleep, That I Feel Greatly Astonished; And In Amazement I Almost Persuade Myself That I Am Now Dreaming.

Desire Awakens Only To Things That Are Thought Possible.
