Its manifestations are, therefore, strictly necessary, and it is absolutely impossible to be other than as it is. In every moment of her duration nature is one connected whole, in every moment must every individual be what it is because all others are what they are, and a single grain of sand could not be moved from its place, without, however imperceptibly to us, changing something throughout all parts of the immeasurable whole. Every moment of duration is determined by all past moments, and will determine all future movements, and even the position of a grain of sand cannot be conceived other than it is, without supposing other changes to an indefinite extent. Let us imagine that grain of sand to be lying some few feet further inland than it actually does; then must the storm-wind that drove it in from the sea-shore have been stronger than it actually was; then must the preceding state of the atmosphere, by which this wind was occasioned, and its degree of strength being determined, have been different from what it actually was, and the preceding changes which gave rise to this particular weather, and so on. We must suppose a different temperature from that which really existed--a different constitution of bodies which influenced that temperature. How can we know that in such a state of weather we have been supposing, in order to carry this grain of sand a few yards further, some ancestors of yours might not have perished from hunger, cold, or heat, long before the birth of that son from whom you are descended, and thus you might never have been at all, and all that you have done, and all that you ever hope to do, must have been hindered, in order that a grain of sand might lie in a different place." * The whole of the first book is devoted to the necessitated condition of man in relation to the universe. In one portion there is a succession of beautiful similes, portraying the blissful state we are in, instead of being gifted with finer sensibilities, or a prescience, which would be a curse. * Fichte's "Destination of Man," pp. 8, 9
