“The Cloud of Unknowing was written by someone who was exceedingly tough-minded in the sense in which William James used the phrase. He was most unsentimental, matter of fact, and down to earth; and he regarded this habit of mind as a prerequisite for the work in which he was engaged. He proceeded upon the belief that when an individual undertakes to bring his life into relation to God, he is embarking upon a serious and demanding task, a task that leaves no leeway for self-deception or illusion. It requires the most rigorous dedication and self-knowledge. The Cloud of Unknowing is therefore a book of strong and earnest thinking. It makes a realistic appraisal of the problems and weaknesses of individual human beings, for it regards man's imperfections as the raw material to be worked with in carrying out the discipline of spiritual development.”

“Earthly friends may alter their minds regarding the work in which we are engaged; but if indeed we work for God, whoever may alter His mind regarding our service, He will not. Earthly friends may lose their ability to help us, however much they desire so to do; but He remains throughout eternity the infinitely Rich One.”

“In all of knowable reality, God is unique. He is knowable not like the multiplication table or the table of elements; he alone is knowable as the one totally in control of being known. He is not at the disposal of the human mind. He is known when he wills to be known. Yet he is known in and through created reality, which is known naturally. Therefore the glory of God is exalted most not when we know God apart from observation and reading and study, but when we know God as a result of his free and gracious self-revelation in and through our earnest observation of and meditation on his work and Word in history.”

“The human being is a very poorly designed machine tool. The human being excels in coordination. He excels in relating perception to action. He works best if the entire human being, muscles, senses, and mind, is engaged in the work.”

“Every trial a man goes through, if he is faithful in that trial and does honor to God and his religion he has espoused, at the end of that trial or affliction that individual is nearer to God, nearer in regard to the increase of faith, wisdom, knowledge and power, and hence is more confident in calling upon the Lord for those things he desires.”

“It is self-evident that the tabula rasa of modernization favors the optimum use of earth-moving equipment inasmuch as a totally flat datum is regarded as the most economic matrix upon which to predicate the rationalization of construction.”
