A man’s upbringing, his talents, his circumstances, are usually a tolerable index of his vocation. If our parents have sent us to Oxford, if out country allows us to remain there, this is prima facie evidence that the life which we, at any rate, can best lead to the glory of God at present is the learned life. By leading that life to the glory of God I do not, of course, mean any attempt to make our intellectual inquiries work out to edifying conclusions. That would be, as Bacon says, to offer to the author of truth the unclean sacrifice of a lie. I mean the pursuit of knowledge and beauty, in a sense, for their own sake, but in a sense which does not exclude their being for God’s sake. An appetite for these things exists in the human mind, and God makes no appetite in vain. We can therefore pursue knowledge as such, and beauty as such, in the sure confidence that by so doing we are either advancing to the vision of God ourselves or indirectly helping others to do so. Humility, no less than the appetite, encourages us to concentrate simply on the knowledge or the beauty, not too much concerning ourselves with their ultimate relevance to the vision of God. That relevance may not be intended for us but for our betters—for men who come after and find the spiritual significance of what we dug out in blind and humble obedience to our vocation…The intellectual life is not the only road to God, nor the safest, but we find it to be a road, and it may be the appointed road for us.
