Nature always wears colours of the spirit.
The earth laughs in flowers.
The eloquent man is he who is no beautiful speaker, but who is inwardly and desperately drunk with a certain belief.
Science does not know its debt to imagination.
No great man ever complains of want of opportunity.
When nature has work to be done, she creates a genius to do it.
The faith that stands on authority is not faith.
No change of circumstances can repair a defect of character.
Every man in his lifetime needs to thank his faults.
Little minds have little worries; big minds have no time for worries.
