It has always been the man ahead that has been called the heretic.
Heresy is the last and best thought always! Heresy extends the
hospitality of the brain to a new idea; that is what the rotting says to
flax growing; that is what the dweller in the swamp says to the man on
the sun-lit hill; that is what the man in the darkness cries out to the
grand man upon whose forehead is shining the dawn of a grander day; that
is what the coffin says to the cradle. Orthodoxy is a kind of shroud,
and heresy is a banner--Orthodoxy is a fog and Heresy a star shining
forever upon the cradle of truth. I do not mean simply in religion, I
mean in everything and the idea I wish to impress upon you is that you
should keep your minds open to all the influences of nature, you should
keep your minds open to reason; hear what a man has to say, and do not
let the turtle-shell of bigotry grow above your brain. Give everybody a
chance and an opportunity; that is all.
