C.N. Douglas, comp. Forty Thousand Quotations: Prose and Poetical. 1917.
What passes in the world for talent or dexterity or enterprise is often only a want of moral principle. We may succeed where others fail, not from a greater share of invention, but from not being nice in the choice of expedients.
Before thy undertaking of any design, weigh the glory of thy action with the danger of the attempt; if the glory outweigh the danger, it is cowardice to neglect it; if the danger exceed the glory, it is rashness to attempt it; if the balances stand poised, let thy own genius cast them.
