One of the best parts of leaving the fight between good and evil behind was it freeing up my mind to think in terms of consequences of actions, reasoning and ethics.
This statement mistakenly assumes that ideas about good and evil eschews the use to the mind. That is, it divorces consequences, reasoning and ethics from morality.
That thought process does not hold up, logically. Indeed, I would call it a false dichotomy. Faith and logic are not diametrically opposed. They can live harmoneously together, and often do. More scientists believe in a G*D than not. In fact, scientists believe in G*D more than any other disciplinarians.
(And historians less than any other disciplines).
Growing is about keeping the mind open to new ideas. And yes, admitting sometimes that we are wrong.
Shalom!
