[1 of 1] Swedenborg (1688-1772, Sweden): primary subject "Polygamy" (search under Outer Life/Culture, Life, Society)": source "Heaven and Hell": detail "Section 379"
Nor is true marriage love possible between one husband and several wives; for its spiritual origin, which is the formation of one mind out of two, is thus destroyed; and in consequence interior conjunction, which is the conjunction of good and truth, from which is the very essence of that love, is also destroyed. Marriage with more than one is like an understanding divided among several wills; or it is like a man attached not to one but to several churches, since his faith is so distracted thereby as to come to naught.
