Albert Einstein

Never do anything against conscience, even if the state demands it.

Nathanael Vincent 03

The true cause why stupid sinners say there is no such thing as conscience, is this, Conscience does accurse, and reproach, and disquiet them, and they first wishing there were no such thing, employ their corrupt reason to argue against it.

William Fenner 02

The Lord engraved conscience in man when he created him at first. True it is, since the fall of man conscience is miserably corrupted; but man can never put it off: Conscience continueth forever in every man whether he be in earth or heaven or hell.

Nathanael Vincent 02

This conscience, when awakened, will deal plainly with the greatest .... Conscience is not to be escaped; we can no more fly from conscience than we can run away from ourselves.

Nathanael Vincent 01

This thing, called conscience, is in everyone; there is no man without it. You may as well suppose a man without an understanding as without a conscience; and without a power to know anything, as without a power to reflect upon himself. Every reasonable soul, being capable both of sin and grace, is endued with a power of reflecting upon itself, that sin may be condemned and grace may be approved. All are called upon to “consider their ways” (Haggai 1:5, 7), but to take our own ways into consideration is the work of conscience; conscience therefore is in all.

But my dreams they aren't as empty

As my conscience seems to be

(From Behind Blue Eyes)

John Milton

Give me the liberty to know, to utter, and to argue freely according to conscience, above all liberties.

Areopagitica

Tolstoy

Wrong does not cease to be wrong because the majority share in it.
A Confession

Martin Luther King Jr

There comes a time when one must take a position that is neither safe, nor politic, nor popular, but he must take it because conscience tells him it is right.

A Testament of Hope: The Essential Writings and Speeches

Salvian of Marseille

What rich man, to repeat my former question, save only a few, is not stained by every sort of evil deed? And when I except a few, would that I might include many more in the exception! for then the innocence of the majority might be the salvation of all. I am speaking about none now save the man who recognizes that my words apply to him. If what I say lies outside his conscience my charge will do him no discredit. If, on the other hand, his heart admits the truth of my words, he should realize that it is not my tongue that is accusing him but his own conscience.
