contrary purpose

I have studied my faith with attention as to its foundations, reading for this purpose books of apologetics as well as those written with a contrary purpose, and trying to appreciate the arguments pro and contra.

Efforts designed to ameliorate the condition of an individual were sure of answering a contrary purpose.

What could be more intelligible than that the inertia of matter, or pure chance, or some contrary purpose, should mar the expression of any platonic idea exercising its magic influence over the world?

The assertion of any principle ruling to the contrary purpose, seems to the multitude of superficial thinkers as a kind of cruelty to the persons, the severity of the natural law being, by an easy slide of thought, laid to the charge of the mere philosopher who detects and announces its operation.

Because speech was given us to express our thoughts; to use this faculty therefore for a contrary purpose is against its nature, against a law of our being, and this is evil.
