Because All The Sick Do Not Recover,

Philosophy Is True Mother Of The Arts [of Science].

Nature Has Lent Us Life At Interest, Like Money, And Has Fixed No Day For Its Payment.

Like Readily Consorts With Like.

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.

There Is No Praise In Being Upright, Where No One Can, Or Tries To Corrupt You.
