But give ear, all ye inhabitants of the land:
"The man who is thoroughly convinced of the universal
operation of the law of causation cannot for a moment entertain the
idea of a being who interferes in the course of events - provided,
of course, that he takes the hypothesis of causality really
seriously. He has no use for the religion of fear and equally little
for social or moral religion. A God who rewards and punishes is
inconceivable to him for the simple reason that a man's actions are
determined by necessity, external and internal, so that in God's
eyes he cannot be responsible, any more than an inanimate object is
responsible for the motions it undergoes. Science has therefore been
charged with undermining morality, but the charge is unjust. A man's
ethical behavior should be based effectually on sympathy, education,
and social ties and needs; no religious basis is necessary.
Man would indeed be in a poor way if he had to be restrained by fear of
punishment and hopes of reward after death."

Rationalists do not require God, or even majority opinion, to make personal decisions about abortion or anything else.
