Some suggestions for you :
Science has fulfilled her function when she has ascertained and enunciated truth.
In scientific work, those who refuse to go beyond fact rarely get as far as fact.
Patience and tenacity of purpose are worth more than twice their weight of cleverness.
Time, whose tooth gnaws away everything else, is powerless against truth.
Logical consequences are the scarecrows of fools and the beacons of wise men.
Proclaim human equality as loudly as you like, Witless will serve his brother.
