Knowledge and wisdom far from being one, have ofttimes no connection. Knowledge is proud that he has learned so much; wisdom is humble that he knows no more.—Cowper

Wish not to taste what doth not to thee fall;
Do well thyself, before thou striv'st to lead,
And truth shall thee deliver without dread.

—Geoffrey Chaucer

Oh, many a shaft, at random sent,
Finds mark the archer little meant!
And many a word at random spoken,
May soothe, or wound, a heart that's broken.

—Sir W. Scott

Govern the lips as they were palace doors, the king within. Tranquil and fair and courteous be all words which from that presence win.

—Edwin Arnold

Whene'er a noble deed is wrought,
Whene'er is spoken a noble thought,
Our hearts, in glad surprise,
To higher levels rise.

—Longfellow

Love thyself last; cherish those hearts that hate thee;
Corruption wins not more than honesty.
Still in thy right hand carry gentle peace,
To silence envious tongues; be just, and fear not.
