Apologism is the metaphysical philosophy that argues that it is wrong for humans to attempt to alter the conditions of life in the mortal sphere of influence. It is opposed to the idea that absolute "progress" is a desirable goal for the pursuit of human endeavors.

Apologism stands solidly in opposition to the metaphysics of meliorism, which states that it is one's duty to seek constant betterment of the self.

Apologism is not to be confused with apologetics.
