All this confusion and evil comes of the blindness which cannot know that, beyond the primary animal end of propagation in marriage, there is a secondary but more exalted spiritual end.
It is needless to insist how intimately that secondary end of marriage is bound up with the practice of birth-control.

Without birth-control, indeed, it could frequently have no existence at all, and even at the best seldom be free from disconcerting possibilities fatal to its very essence.

Against these disconcerting possibilities is often placed, on the other side, the un-aesthetic nature of the contraceptives associated with birth-control.

Yet, it must be remembered, they are of a part with the whole of our civilised human life.

We at no point enter the spiritual save through the material.
