"Good can exist without evil, whereas evil cannot exist without good"

This quote by Thomas Aquinas suggests that good is a more effective force than evil. He suggests that good can exist without evil, but evil can not exist without good. This recommends that good is the structure of deep space, and evil is an outcome of the absence of good. Aquinas is suggesting that good is the natural state of the universe, and evil is a discrepancy from that natural state. He is also suggesting that good is a more effective force than wicked, which it is possible to develop a world without evil. This quote is a tip that we need to strive to produce a world where good is the standard, and evil is the exception. It is a suggestion that we ought to strive to produce a world where excellent is the structure, and evil is the aberration.
