I am saying nothing against the charity of Christians; nothing against any kindness or goodness. They may talk of the asylums they have built, but they have not built asylums enough to hold the people who have been driven insane by their teachings.
Orthodox religion has opposed liberty. It has opposed investigation and free thought. If all the churches in Europe had been observatories, if the cathedrals had been universities where facts were taught and where nature was studied, if all the priests had been real teachers, this world would have been far, far beyond what it is today.
There is an idea that Christianity is positive, and Infidelity is negative. If this be so, then falsehood is positive and truth is negative. What I contend is that Infidelity is a positive religion; that Christianity is a negative religion. Christianity denies and Infidelity admits. Infidelity stands by facts; it demonstrates by the conclusions of the reason. Infidelity does all it can to develop the brain and the heart of man. That is positive. Religion asks man to give up this world for one he knows nothing about. That is negative. I stand by the religion of reason. I stand by the dogmas of demonstration.
