Keep clear of psychiatrists unless you know that they are also Christians. Otherwise they start with the assumption that your religion is an illusion and try to ‘cure’ it: and this assumption they make not as professional psychologists but as amateur philosophers.
─C.S. Lewis, in a letter to Mrs. Frank L. Jones, in The Collected Letters of C.S. Lews, vol. 2, Books, Broadcasts, and the War, 1931-1949, 765.
