“Any civilization where the main symbol of religious veneration is a tool of execution is a bad place to have children.”

On Italians, sometimes cited to The Rommel Papers (1953) edited by Basil Henry Liddell Hart, but without specific chapter or page citations; it seems to summarize an attitude indicated by Rommel in Ch. 11 of that work, but no published occurrence of this has actually been located.

Context: 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. To "retract," for example, is to draw back, and when applied to a statement, is symbolic, as much so as a picture of an arm drawn back, to express the same thing, would he. The very word " spirit" means " breath," from the Latin verb spiro, breathe.
