Supernatural religion will fade from this world, and in its
place we shall have reason. In the place of the worship of
something we know not of, will be the religion of mutual love and
assistance — the great religion of reciprocity. Superstition must
go. Science will remain. The church dies hard. The brain of the
world is not yet developed. There are intellectual diseases as well
as physical — there are pestilences and plagues of the mind.
Robert Green Ingersoll – “Orthodoxy”(1884)
