What Is Conscience?

Conscience: a person’s moral sense of right and wrong that guides their behaviour. Inner knowledge, from Latin conscire, ‘with’ + scire ‘know’.

What else could conscience be? 🙂
Does it speak to us?
What if that which people call ‘God’ is just conscience?

Were books written thousands of years ago that changed inner knowledge into thought?
Knowledge is a fact; thought is an interpretation.
