Cowardice asks the question, 'Is it safe?'

Expediency asks the question, 'Is it politic?'

Vanity asks the question, 'Is it popular?'

But, conscience asks the question, 'Is it right?'

And there comes a time when one must take a position that is neither safe, nor politic, nor popular but one must take it because one's conscience tells one that it is right.
