Conscience
This is another related concept, in this discussion. What is it? Is it a Real Thing, or a human construct, imposed upon a pliable herd? Conscience is closely related to morality. It is the 'thing' within humans that reflects the inner, felt morality. It provides the 'sting' when it is violated. It could be correlated to pain, the negative feedback our body gives when we do something injurious to ourselves. In the same way, conscience provides negative feedback when we injure it by violating it's sensitivity.
As usual, I'll give a dictionary definition, in the context of this thread.
Conscience:
the sense or consciousness of the moral goodness or blameworthiness of one's own conduct, intentions, or character together with a feeling of obligation to do right or be good
All of the terms used in these definitions are steeped in moralizing undertones. 'Sense', 'moral goodness', 'do right', etc, ALL reflect the underlying assumption of common knowledge of these things. 'Good' carries a moral judgement, as well as 'bad'. Nobody is confused, or thinks that murder, theft, lying, etc are 'good!', and bravery, honesty, and altruistic acts are 'bad!'
So there is a common base of communication, even crossing language, culture, race, and time. You can ask anyone, in any culture, era, or region, to list 'good & bad!' things, and they will very nearly correlate. There may be a few specifics, or arbitrary cultural mores that vary, but the core elements of morality are consistent and constant, throughout the human experience.
An Indian might have, 'eaten by tiger' as bad, while a pacific islander might use shark. But the basics, murder, theft, assault, fraud, lying; are universally held in disdain by the human collective. I know of no culture or society where these things are esteemed as virtues.
On the 'good' side, bravery, hard work, altruistic acts, kindness, honesty, helping in time of need, and personal responsibility are universally esteemed and held as virtuous, among human beings.
I haven't had many quotes in this thread, but i will rectify that immediately.
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. ~Martin Luther King Jr
Through pride we are ever deceiving ourselves. But deep down below the surface of the average conscience a still, small voice says to us, something is out of tune. ~Carl Gustav Jung
The only tyrant I accept in this world is the 'still small voice' within me. And even though I have to face the prospect of being a minority of one, I humbly believe I have the courage to be in such a hopeless minority. ~Mahatma Gandhi
The torture of a bad conscience is the hell of a living soul. ~John Calvin
It is neither right nor safe to go against my conscience. ~Martin Luther
A clear conscience is the sure sign of a bad memory. ~Mark Twain
On some positions, Cowardice asks the question, “Is it safe?” Expediency asks the question, “Is it politic?” And Vanity comes along and asks the question, “Is it popular?” But Conscience asks the question, “Is it right?”... The ultimate measure of a man is not where he stands in moments of convenience, but where he stands in moments of challenge, moments of great crisis and controversy. ~Martin Luther King Jr.
