All Is To Be Doubted.

Reason Is Nothing Without Imagination.

I Know That I Exist; The Question Is, What Is This 'i' That 'i' Know.

It Is Contrary To Reasoning To Say That There Is A Vacuum Or Space In Which There Is Absolutely Nothing.

Everybody Thinks Himself So Well Supplied With Common Sense That Even Those Most Difficult To Please. . . Never Desire More Of It Than They Already Have.

I Experienced In Myself A Certain Capacity For Judging Which I Have Doubtless Received From God, Like All The Other Things That I Possess; And As He Could Not Desire To Deceive Me, It Is Clear That He Has Not Given Me A Faculty That Will Lead Me To Err If I Use It Aright.
