Excerpts from "There is No Natural Religion," part one, by William Blake
The argument: Man has no notion of moral fitness but from education. Naturally he is only a natural organ subject to sense… Man’s desires are limited by his perceptions; none can desire what he has not perceived. The desires & perceptions of man, untaught by anything but organs of sense, must be limited to objects of sense.
Conclusion: If it were not for the poetic or prophetic character the philosophic & experimental would soon be at the ratio of all things, and stand still, unable to do other than repeat the same dull round over again.
