I spent the two and one-half months between my meeting with the Art Commission and the beginning of my actual mural work in soaking up impressions of the productive activities of the city. I studied industrial scenes by night as well as by day, making literally thousands of sketches of towering blast furnaces, serpentine conveyor belts, impressive scientific laboratories, busy assembling rooms; also of precision instruments, some of them massive yet delicate; and of the men who worked them all. I walked for miles through the immense workshops of the Ford, Chrysler, Edison, Michigan Alkali, and Parke-Davis plants. I was afire with enthusiasm. My childhood passion for mechanical toys had been transmuted to a delight in machinery for its own sake and for its meaning to man -- his self-fulfillment and liberation from drudgery and poverty. That is why now I placed the collective hero, man-and-machine, higher than the old traditional heroes of art and legend. I felt that in the society of the future as already, to some extent, that of the present, man-and-machine would be as important as air, water, and the light of the sun.This was the "philosophy," the state of mind in which I undertook my Detroit frescoes.
It has been the practice of all Christian commentators on the Bible, and of all Christian priests and preachers, to impose the Bible on the world as a mass of truth, and as the word of God; they have disputed and wrangled, and have anathematized each other about the supposable meaning of particular parts and passages therein; one has said and insisted that such a passage meant such a thing, another that it meant directly the contrary, and a third, that it meant neither one nor the other, but something different from both; and this they have called understanding the Bible.It has happened, that all the answers that I have seen to the former part of 'The Age of Reason' have been written by priests: and these pious men, like their predecessors, contend and wrangle, and understand the Bible; each understands it differently, but each understands it best; and they have agreed in nothing but in telling their readers that Thomas Paine understands it not.
Loving, of enemies is another dogma of feigned morality, and has besides no meaning. It is incumbent on man, as a moralist, that he does not revenge an injury; and it is equally as good in a political sense, for there is no end to retaliation; each retaliates on the other, and calls it justice: but to love in proportion to the injury, if it could be done, would be to offer a premium for a crime. Besides, the word enemies is too vague and general to be used in a moral maxim, which ought always to be clear and defined, like a proverb. If a man be the enemy of another from mistake and prejudice, as in the case of religious opinions, and sometimes in politics, that man is different to an enemy at heart with a criminal intention; and it is incumbent upon us, and it contributes also to our own tranquillity, that we put the best construction upon a thing that it will bear. But even this erroneous motive in him makes no motive for love on the other part; and to say that we can love voluntarily, and without a motive, is morally and physically impossible.Morality is injured by prescribing to it duties that, in the first place, are impossible to be performed, and if they could be would be productive of evil; or, as before said, be premiums for crime. The maxim of doing as we would be done unto does not include this strange doctrine of loving enemies; for no man expects to be loved himself for his crime or for his enmity.Those who preach this doctrine of loving their enemies, are in general the greatest persecutors, and they act consistently by so doing; for the doctrine is hypocritical, and it is natural that hypocrisy should act the reverse of what it preaches. For my own part, I disown the doctrine, and consider it as a feigned or fabulous morality; yet the man does not exist that can say I have persecuted him, or any man, or any set of men, either in the American Revolution, or in the French Revolution; or that I have, in any case, returned evil for evil.
