Nature Herself Makes The Wise Man Rich.

The Searching-out And Thorough Investigation Of Truth Ought To Be The Primary Study Of Man.

A Man Would Have No Pleasures In Discovering All The Beauties Of The Universe, Even In Heaven Itself, Unless He Had A Partner To Whom He Might Communicate His Joys.

Always The Same Thing.

It Is Not Enough Merely Possess Virtue, As If It Were An Art; It Should Be Practiced.

Through Doubt We Arrive At The Truth.
