The Problem of Evil

If the Cosmic Designer is the theistic, omnipotent and benevolent God, then why is the world so full of evil? Mass destruction/War Disease Creatures torturing and killing other creatures Disco Pain Illness

Why would a benevolent God let such things happen?

Why would an omnipotent God create a world where such things have to happen?

Efficient Cause Aristotle, Aquinas and the causal

argument If A causes B, and B causes C, then A

causes C But what happens if A does not occur?

Neither B nor C will occur either The causal chain must, therefore, have a

beginning, and that beginning is God God is A

From Possibility to Necessity In Nature things that are possible are either,

to be - they are created, or not to be, they are destroyed

If at one time nothing was in existence, it would have been impossible for anything to have begun to exist Big Bang Theory?

Every necessary thing is caused by another God caused everything to exist “Creator” Theory

by design Who ordered things to their end, directed

them, God, in the same way that “the arrow is directed by the archer”
