Substantiation Quotes

PROUN is understood as the creative construction of form (based on the mastery of space) assisted by economic construction of the applied material. The goal of PROUN is progressive movement on the way to concrete creation, and not the substantiation, explanation, or promotion of life. (El Lissitsky)
Faith is, indeed, most necessary in human affairs, as well as in religion Without faith, no contracts could be concluded, nor could any business be transacted. And without faith, where would be the basis for the divine reward of human merit? As it is, that faith which embraces the truths of religion deserves reward. Such faith is, according to the Apostle, "a substantiation of things to be hoped for, a testimonial to things that appear not." View quote
