Joseph Fielding Smith
"The worship of reason, of false philosophy, is greater now than it was [in the past]. Men are depending upon their own research to find out God, and that which they cannot discover and which they cannot demonstrate to their satisfaction through their own research and their natural senses, they reject. They are not seeking for the Spirit of the Lord; they are not striving to know God in the manner in which he has marked out by which he may be known; but they are walking in their own way, believing in their own man-made philosophies, teaching the doctrines of devils and not the doctrines of the Son of God. (Doctrines of Salvation, vol. 3, p. 275)
