“I call those men worldly, earthly, or coarse, whose hearts and minds are wholly fixed on this earth, that small part of the universe they are placed in; who value and love nothing beyond it; whose minds are as cramped as that narrow spot of ground they call their estate, of which the extent is measured, the acres are numbered, and the limits well known. I am not astonished that men who lean, as it were, on an atom, should stumble at the smallest efforts they make for discovering the truth; that, being so short-sighted, they do not reach beyond the heavens and the stars, to contemplate God Himself; that, not being able to perceive the excellency of what is spiritual, or the dignity of the soul, they should be still less sensible of the difficulty of satisfying it; how very inferior the entire world is in comparison to it; how necessary is to it an all-perfect Being, which is God; and how absolutely it needs a religion to find out that God, and to be assured of His reality. I can easily understand that incredulity or indifference are but natural to such men, that they make use of God and religion only as a piece of policy, as far as they may be conducive to the order and decorum of this world, the only thing in their opinion worth thinking of.”

Context: My personal theology is described in the Gifford lectures that I gave at Aberdeen in Scotland in 1985, published under the title, Infinite In All Directions. Here is a brief summary of my thinking. The universe shows evidence of the operations of mind on three levels. The first level is elementary physical processes, as we see them when we study atoms in the laboratory. The second level is our direct human experience of our own consciousness. The third level is the universe as a whole. Atoms in the laboratory are weird stuff, behaving like active agents rather than inert substances. They make unpredictable choices between alternative possibilities according to the laws of quantum mechanics. It appears that mind, as manifested by the capacity to make choices, is to some extent inherent in every atom. The universe as a whole is also weird, with laws of nature that make it hospitable to the growth of mind. I do not make any clear distinction between mind and God. God is what mind becomes when it has passed beyond the scale of our comprehension. God may be either a world-soul or a collection of world-souls. So I am thinking that atoms and humans and God may have minds that differ in degree but not in kind. We stand, in a manner of speaking, midway between the unpredictability of atoms and the unpredictability of God. Atoms are small pieces of our mental apparatus, and we are small pieces of God's mental apparatus. Our minds may receive inputs equally from atoms and from God. This view of our place in the cosmos may not be true, but it is compatible with the active nature of atoms as revealed in the experiments of modern physics. I don't say that this personal theology is supported or proved by scientific evidence. I only say that it is consistent with scientific evidence.

Context: We hear often of the distress of the negro servants, on the loss of a kind master; and with good reason, for no creature on God's earth is left more utterly unprotected and desolate than the slave in these circumstances.
The child who has lost a father has still the protection of friends, and of the law; he is something, and can do something, — has acknowledged rights and position; the slave has none. The law regards him, in every respect, as devoid of rights as a bale of merchandise. The only possible acknowledgment of any of the longings and wants of a human and immortal creature, which are given to him, comes to him through the sovereign and irresponsible will of his master; and when that master is stricken down, nothing remains.
The number of those men who know how to use wholly irresponsible power humanely and generously is small. Everybody knows this, and the slave knows it best of all; so that he feels that there are ten chances of his finding an abusive and tyrannical master, to one of his finding a considerate and kind one. Therefore is it that the wail over a kind master is loud and long, as well it may be.
