Context

“and things are only good, in so far as they aid man in his enjoyment of the intellectual life, which is defined by intelligence. Contrariwise, whatsoever things hinder man's perfecting of his reason, and capability to enjoy the rational life, are alone called evil. VI. As all things whereof man is the efficient cause are necessarily good, no evil can befall man except through external causes; namely, by virtue of man being a part of universal nature, whose laws human nature is compelled to obey, and to conform to in almost infinite ways. VII. It is impossible, that man should not be a part of nature, or that he should not follow her general order;” source
