"Conscience itself asserts that it is a voice of God."
-Carl G. Jung (1875-1961)
"Conscience is God's presence in man."
-Emmanuel Swedenborg (1688-1772)
If conscience is that still small voice inside our heads, where does it come from? Who put it there? Our conscience is strong, and speaks to us loudly enough that we can't ignore it. It commands us to pay attention.
