It seems as if parents of the christian profession were ashamed to tell their children any thing about the principles of their religion. They sometimes instruct them in morals, and talk to them of the goodness of what they call Providence; for the Christian mythology has five deities: there is God the Father, God the Son, God the Holy Ghost, the God Providence, and the Goddess Nature. But the christian story of God the Father putting his son to death, or employing people to do it, (for that is the plain language of the story,) cannot be told by a parent to a child; and to tell him that it was done to make mankind happier and better, is making the story still worse; as if mankind could be improved by the example of murder; and to tell him that all this is a mystery, is only making an excuse for the incredibility of it.

How different is this to the pure and simple profession of Deism! The true deist has but one Deity; and his religion consists in contemplating the power, wisdom, and benignity of the Deity in his works, and in endeavouring to imitate him in every thing moral, scientifical, and mechanical.

The religion that approaches the nearest of all others to true Deism, in the moral and benign part thereof, is that professed by the quakers: but they have contracted themselves too much by leaving the works of God out of their system. Though I reverence their philanthropy, I can not help smiling at the conceit, that if the taste of a quaker could have been consulted at the creation, what a silent and drab-colored creation it would have been! Not a flower would have blossomed its gaieties, nor a bird been permitted to sing.

Quitting these reflections, I proceed to other matters. After I had made myself master of the use of the globes, and of the orrery, [NOTE by Paine: As this book may fall into the bands of persons who do not know what an orrery is, it is for their information I add this note, as the name gives no idea of the uses of the thing. The orrery has its name from the person who invented it. It is a machinery of clock-work, representing the universe in miniature: and in which the revolution of the earth round itself and round the sun, the revolution of the moon round the earth, the revolution of the planets round the sun, their relative distances from the sun, as the center of the whole system, their relative distances from each other, and their different magnitudes, are represented as they really exist in what we call the heavens.—Author.] and conceived an idea of the infinity of space, and of the eternal divisibility of matter, and obtained, at least, a general knowledge of what was called natural philosophy, I began to compare, or, as I have before said, to confront, the internal evidence those things afford with the christian system of faith.

Though it is not a direct article of the christian system that this world that we inhabit is the whole of the habitable creation, yet it is so worked up therewith, from what is called the Mosaic account of the creation, the story of Eve and the apple, and the counterpart of that story, the death of the Son of God, that to believe otherwise, that is, to believe that God created a plurality of worlds, at least as numerous as what we call stars, renders the christian system of faith at once little and ridiculous; and scatters it in the mind like feathers in the air. The two beliefs can not be held together in the same mind; and he who thinks that he believes both, has thought but little of either.

Though the belief of a plurality of worlds was familiar to the ancients, it is only within the last three centuries that the extent and dimensions of this globe that we inhabit have been ascertained. Several vessels, following the tract of the ocean, have sailed entirely round the world, as a man may march in a circle, and come round by the contrary side of the circle to the spot he set out from. The circular dimensions of our world, in the widest part, as a man would measure the widest round of an apple, or a ball, is only twenty-five thousand and twenty English miles, reckoning sixty-nine miles and an half to an equatorial degree, and may be sailed round in the space of about three years. [NOTE by Paine: Allowing a ship to sail, on an average, three miles in an hour, she would sail entirely round the world in less than one year, if she could sail in a direct circle, but she is obliged to follow the course of the ocean.—Author.]

A world of this extent may, at first thought, appear to us to be great; but if we compare it with the immensity of space in which it is suspended, like a bubble or a balloon in the air, it is infinitely less in proportion than the smallest grain of sand is to the size of the world, or the finest particle of dew to the whole ocean, and is therefore but small; and, as will be hereafter shown, is only one of a system of worlds, of which the universal creation is composed.

It is not difficult to gain some faint idea of the immensity of space in which this and all the other worlds are suspended, if we follow a progression of ideas. When we think of the size or dimensions of, a room, our ideas limit themselves to the walls, and there they stop. But when our eye, or our imagination darts into space, that is, when it looks upward into what we call the open air, we cannot conceive any walls or boundaries it can have; and if for the sake of resting our ideas we suppose a boundary, the question immediately renews itself, and asks, what is beyond that boundary? and in the same manner, what beyond the next boundary? and so on till the fatigued imagination returns and says, there is no end. Certainly, then, the Creator was not pent for room when he made this world no larger than it is; and we have to seek the reason in something else.

If we take a survey of our own world, or rather of this, of which the Creator has given us the use as our portion in the immense system of creation, we find every part of it, the earth, the waters, and the air that surround it, filled, and as it were crowded with life, down from the largest animals that we know of to the smallest insects the naked eye can behold, and from thence to others still smaller, and totally invisible without the assistance of the microscope. Every tree, every plant, every leaf, serves not only as an habitation, but as a world to some numerous race, till animal existence becomes so exceedingly refined, that the effluvia of a blade of grass would be food for thousands.

Since then no part of our earth is left unoccupied, why is it to be supposed that the immensity of space is a naked void, lying in eternal waste? There is room for millions of worlds as large or larger than ours, and each of them millions of miles apart from each other.
