Dogmatism Is The Greatest Of Mental Obstacles

The Fact That An Opinion Has Been Widely Held Is No Evidence Whatever That It Is Not Utterly Absurd.

Freedom Of Opinion Can Only Exist When The Government Thinks Itself Secure.

I Should Like To Believe My People's Religion, Which Was Just What I Could Wish, But Alas, It Is Impossible. I Have Really No Religion, For My God, Being A Spirit Shown Merely By Reason To Exist, His Properties Utterly Unknown, Is No Help To My Life. I Have Nor The Parson's Comfortable Doctrine That Every Good Action Has Its Reward, And Every Sin Is Forgiven. My Whole Religion Is This: Do Every Duty, And Expect No Reward For It, Either Here Or Hereafter.

I Think We Ought Always To Entertain Our Opinions With Some Measure Of Doubt. I Shouldn't Wish People Dogmatically To Believe Any Philosophy, Not Even Mine.

My Own View On Religion Is That Of Lucretius. I Regard It As A Disease Born Of Fear And As A Source Of Untold Misery To The Human Race.
