Conscience - christiansquoting.org.uk
A guilty conscience needs no accuser.
Conscious is when you are aware of something, and conscience is when you wish you weren't.
A well-beaten path does not always make the right road.
There is not pillow so soft as a clear conscience. --French Proverb
It is not given to human beings [...] to foresee or predict to any large extent the unfolding course of events. In one phase men seem to have been right, in another they seem to have been wrong. Then again, a few years later, when the perspective of time has lengthened, all stands in a different setting. There is a new proportion. There is another scale of values. History with its flickering lamp stumbles along the trail of the past, trying to reconstruct its scenes, to revive its echoes and kindle with pale gleams the glory of former days. What is the worth of all this? The only guide to a man is his conscience, the only shield to his memory is the rectitude and the sincerity of his actions. It is very imprudent to walk through life without this shield, because we are so often mocked by the failure of our hopes and the upsetting of our calculations; but with this shield, however the fates may play, we march always in the ranks of honour. -Part of Winston Churchill's eulogy for Neville Chamberlain Their Finest Hour, Page 486
A good conscience is a continual Christmas. - Benjamin Franklin (1706-1790) _Poor Richard's Almanac _
In matters of conscience, the law of the majority has no place. --- Mohandas Karamchand Gandhi
The inner voice is at once our greatest danger and an indispensable help.--Carl G. Jung (1875-1961)_The Development of Personality_ 
Cowardice asks the question, "Is it safe?"
Expedience asks the question, "Is it political?"
Vanity asks, "Is it popular?"
But conscience asks the question, "Is it right?"
There comes a time when one must take a position that's neither safe, nor political, nor popular, but he must make it because his conscience tells him that it's right. -- Martin Luther King Jr.
Unless I am convicted by scripture and plain reason -- I do not accept the authority of the popes and councils, for they have contradicted each other -- my conscience is captive to the Word of God. I cannot and I will not recant anything for to go against conscience is neither right nor safe. God help me. Amen.
Martin Luther, at the Imperial Diet at Worms, 18 April 1521.
Conscience is the still small voice that can make you feel still smaller. -B. Phillips
A bad conscience embitters the sweetest comforts; a good conscience sweetens the bitterest crosses. --Wendell Phillips
To say of an act done, "My conscience is quite clear", sounds smug and satisfactory. It does not by any means follow that the speaker's conscience ought to be clear. It may simply show that [it] is sadly unenlightened. ... G. E. Reindorp
At times, although one is perfectly in the right, one's legs tremble; at other times, although one is completely in the wrong, birds sing in one's soul.
Vasily V. Rozanov Russian philosopher
Conscience is the voice of the soul; the passions are the voice of the body. --J. J. Rousseau
Conscience: The still small voice that makes you feel still smaller. --James A. Sanaker

A peace above all earthly dignities,
A still and quiet conscience.
Shakespeare, _Henry VIII_
A person may sometimes have a clear conscience simply because his head is empty. --Ralph W. Sockman, _How to Believe_, 1953
The voice of conscience is so delicate that it is easy to stifle it; but it is also so clear that it is impossible to mistake it. --Germaine de Stael (1766-1817)
