Besides, it is not fair to make the Catholic support a Protestant school, nor is it just to collect taxes from infidels and atheists to support schools in which any system of religion is taught.
The sciences are not sectarian. People do not persecute each other on account of disagreements in mathematics. Families are not divided about botany, and astronomy does not even tend to make a man hate his father and mother. It is what people do not know, that they persecute each other about. Science will bring, not a sword, but peace.
Just as long as religion has control of the schools, science will be an outcast. Let us free our institutions of learning. Let us dedicate them to the science of eternal truth. Let us tell every teacher to ascertain all the facts he can—to give us light, to follow Nature, no matter where she leads; to be infinitely true to himself and us; to feel that he is without a chain, except the obligation to be honest; that he is bound by no books, by no creed, neither by the sayings of the dead nor of the living; that he is asked to look with his own eyes, to reason for himself without fear, to investigate in every possible direction, and to bring us the fruit of all his work.
