There are depths in man which go down the length of the lowest Hell, as there are heights which reach the highest Heaven; — for are not both Heaven and Hell made out of him, everlasting Miracle and Mystery that he is?

This was slightly paraphrased in A Dictionary of Thoughts : Being a Cyclopedia of Laconic Quotations from the Best Authors, Both Ancient and Modern (1891) edited by Tryon Edwards. p. 327. This version in turn was referenced by Martin Luther King, Jr. in his Detroit sermon "The Christian Doctrine of Man" (12 March 1958) | There are depths in man that go to the lowest hell, and heights that reach the highest heaven, for are not both heaven and hell made out of him, everlasting miracle and mystery that he is.
