Conscience is the internal perception of the rejection of a particular wish operating in us.

Conscience is the authentic voice of God to you.

Conscience is the voice of God.

Conscience is the inner voice that warns us somebody may be looking.

Conscience is a Jewish invention.

Conscience is, in most men, an anticipation of the opinions of others.

I note that a common but faulty view is that, like a satellite navigator, conscience gives us directions from outside our own moral reasoning. The classical Christian conception of conscience is of the natural perception of basic moral principles, their application in particular circumstances, and the final judgment about what is to be (or has been) done. Without shared objective principles, "conscientious" belief becomes window-dressing for the raw expression of preference or power. But conscience must be both well-informed and well-formed if it is to be a reliable guide to action.

Conscience is a God to all mortals.

Conscience is a mother-in-law whose visit never ends.

Conscience is the aboriginal Vicar of Christ, a prophet in its informations, a monarch in its peremptoriness, a priest in its blessings and anathemas, and, even though the eternal priesthood throughout the Church could cease to be, in it the sacerdotal principle would remain and would have a sway.

Conviction is the Conscience of the Mind.

Freedom is inseparable from conscience. And even if it is true that all the ideas developed by the social conciousness are the product of evolution, conscience at least has nothing to do with the historic process. Conscience, both as a sense and as a concept, is a priori immanent in man, and shakes the very foundations of the society that has emerged from our ill-conceived civilisation.

Modernity has identified the theme of conscience as one of its most emblematic frontiers. [...] Too often, in culture as in life, the concept of conscience, that is, the ability of a person to recognise the truth and the decision to follow it, is confused with the ultimate peremptory nature of subjective opinion.

Some good must come by clinging to the right. Conscience is a man's compass, and though the needle sometimes deviates, though one often perceives irregularities in directing one's course by it, still one must try to follow its direction.
