Quote by Robert Boyle

"The usefulness of a cupboard were not to be measured by the number of utensils it contained, but by the readiness with which the right instrument could be found and used."

"A man is not to be credited for what he does by constraint and necessity."

"I have always thought it a very foolish question to ask a man, what he would not do for a considerable sum of money."

"Nothing can be more futile than to attempt to advance science by the method of unfounded conjecture."
