“For want of clearer knowledge of this subject, we are obliged to content ourselves with terms that convey only negative ideas, and to say that God is a being untreated or uncaused; and this is all that we mean when we sometimes say that he is self existent.”
Vol. I : Part I : The Being and Attributes of God, § 1 : Of the existence of God, and those attributes which art deduced from his being considered as uncaused himself, and the cause of every thing else (1772)

Context: It may, perhaps, be true, though we cannot distinctly see it to be so, that as all finite things require a cause, infinites admit of none. It is evident, that nothing can begin to be without a cause; but it by no means follows from thence, that that must have had a cause which had no beginning. But whatever there may be in this conjecture, we are constrained, in pursuing the train of causes and effects, to stop at last at something uncaused.
That any being should be self created is evidently absurd, because that would suppose that he had a being before he had, or that he existed, and did not exist at the same time. For want of clearer knowledge of this subject, we are obliged to content ourselves with terms that convey only negative ideas, and to say that God is a being untreated or uncaused; and this is all that we mean when we sometimes say that he is self existent.

Context: Only within this kind of life does a spoken prayer make sense. A prayer in church, at table or in school is only a witness to what we want to make of our entire lives. Such a prayer reminds us that praying is living and it invites us to make this an ever-greater reality. Thus, there are as many ways to pray as there are moments in life. Sometimes we seek out a quiet spot and want to be alone, sometimes we look for a friend and want to be together. Sometimes we like a book, sometimes we prefer music. Sometimes we want to sing out with hundreds, sometimes only whisper with a few. Sometimes we want to say it with words, sometimes with a deep silence.

Context: It seems to me that the idea of a personal God is an anthropomorphic concept which I cannot take seriously. I feel also not able to imagine some will or goal outside the human sphere. My views are near to those of Spinoza: admiration for the beauty of and belief in the logical simplicity of the order and harmony which we can grasp humbly and only imperfectly. I believe that we have to content ourselves with our imperfect knowledge and understanding and treat values and moral obligations as a purely human problem—the most important of all human problems.
