"All religious expression is symbolism; since we can describe only what we see, and the true objects of religion are The Seen. The earliest instruments of education were symbols; and they and all other religious forms differed and still differ according to external circumstances and imagery, and according to differences of knowledge and mental cultivation. All language is symbolic, so far as it is applied to mental and spiritual phenomena and action. All [[words]' have, primarily, a material sense, howsoever they may afterward get, for the ignorant, a spiritual non-sense."
