What conscience is

3. And, first, what are we to understand by conscience? What is the meaning of this word that is in every one’s mouth? One would imagine, it was an exceeding difficult thing, to discover this, when we consider, how large and numerous volumes have been from time to time wrote on this subject: and how all the treasures of ancient and modern learning have been ransack’d, in order to explain it. And yet it is to be fear’d, it has not received much light from all those elaborate enquiries. Rather, have not most of those writers puzzled the cause; darkening counsel by words without knowledge; perplexing a subject, plain in itself, and easy to be understood? For set aside but hard words, and every man of an honest heart will soon understand the thing.

4. God has made us thinking beings, capable of perceiving what is present, and of reflecting or looking back on what is past. In particular, we are capable of perceiving, whatsoever passes in our own hearts or lives; of knowing whatsoever we feel or do; and that either while it passes, or when it is past. This we mean when we say, man is a conscious being: he hath a consciousness or inward perception both of things present and past relating to himself, of his own tempers and outward behaviour. But what we usually term conscience, implies, somewhat more than this. It is not barely, the knowledge of our present, or the remembrance of our preceding life. To remember, to bear witness either of past or present things, is only one, and the least office of conscience. Its main business is to excuse or accuse, to approve or disapprove, to acquit or condemn.

5. Some late writers indeed have given a new name to this, and have chose to stile it, a moral sense. But the old word seems preferable to the new, were it only on this account, that it is more common and familiar among men, and therefore easier to be understood. And to Christians it is undeniably preferable on another account also; namely, because it is scriptural; because it is the word which the wisdom of God hath chose to use in the inspired writings.

And according to the meaning wherein it is generally used there, particularly in the epistles of St. Paul, we may understand by conscience, a faculty or power, implanted by God in every soul that comes into the world, of perceiving what is right or wrong in his own heart or life, in his tempers, thoughts, words and actions.
