There is no god and there is no soul. Hence, there is no need for the props of traditional religion. With dogma and creed excluded, then immutable truth is dead and buried. There is no room for fixed and natural law or permanent moral absolutes.
Conflict is the gadfly of thought. It stirs us to observation and memory. It instigates to invention. It shocks us out of sheeplike passivity, and sets us at noting and contriving.
