President Gordon B. Hinckley described the weakness of trusting intellect over faith:
“The intellect is not the only source of knowledge. There is a promise, given under the inspiration of the Almighty, set forth in these beautiful words: ‘God shall give unto you knowledge by his holy Spirit, yea, by the unspeakable gift of the Holy Ghost’ (D&C 121:26).
“The humanists who criticize us, the so-called intellectuals who demean us, speak only from ignorance of this manifestation. They have not heard the voice of the Spirit. They have not heard it because they have not sought after it and prepared themselves to be worthy of it. Then, supposing that knowledge comes only of reasonings and of the workings of the mind, they deny that which comes by the power of the Holy Ghost. …
“Do not be trapped by the sophistry of the world, which for the most part is negative and which seldom, if ever, bears good fruit. Do not be ensnared by those clever ones whose self-appointed mission it is to demean that which is sacred, to emphasize human weakness, and undermine faith, rather than inspire strength” (“Be Not Afraid, Only Believe” [CES fireside for young adults, Sept. 9, 2001], 4, www.ldsces.org).
