The first and last lesson of religion is, "The things that are seen, are temporal; the things that are unseen, are eternal." It puts an affront upon nature.
If everyone will try to understand the core of his own religion and adhere to it, and will not allow false teachers to dictate to him, there will be no room left for quarrelling.
For first of all we must prepare a Natural and Experimental History, sufficient and good; and this is the foundation of all; for we are not to imagine or suppose, but to discover, what nature does or may be made to do.
The religion that is afraid of science dishonors God and commits suicide. Every influx of atheism, of skepticism, is thus made useful as a mercury pill assaulting and removing a diseased religion, and making way for truth.
