Whatever Is Immediately Perceived Is An Idea:

I Do Not Deny The Existence Of Material Substance Merely Because I Have No Notion Of It, But Because The Notion Of It Is Inconsistent, Or In Other Words, Because It Is Repugnant That There Should Be A Notion Of It.

How Often Must I Repeat, That I Know Or Am Conscious Of My Own Being; And That I Myself Am Not My Ideas, But Somewhat Else, A Thinking, Active Principle That Perceives, Knows, Wills, And Operates About Ideas?

All That Stock Of Arguments [the Skeptics] Produce To Depreciate Our Faculties, And Make Mankind Appear Ignorant And Low, Are Drawn Principally From This Head, To Wit, That We Are Under An Invincible Blindness As To The True And Real Nature Of Things.

To Be A Good Patriot, A Man Must Consider His Countrymen As God's Creatures, And Himself As Accountable For His Acting Towards Them.

For My Own Private Satisfaction, I Had Rather Be Master Of My Own Time Than Wear A Diadem.
