My poor head is in such a whirl, my mind is all in bits.

The finished man, you know, is difficult to please; a growing mind will ever show you gratitude. --Faust 1, lines 182-3

The greatest genius will not be worth much if he pretends to draw exclusively from his own resources

A noble man is led by woman's gentle words.

You accuse a woman of wavering affections, but don't blame her; she is just looking for a consistent man.

A good man, through obscurest aspirations Has still an instinct of the one true way.

With knowledge comes more doubt.
