attracts, the north repels. To empty here, you must condense there. An inevitable dualism bisects nature, so that each thing is a half, and suggests another thing to make it whole; as, spirit, matter; man, woman; odd, even; subjective, objective; in, out; upper, under; motion, rest; yea, nay.
Whilst the world is thus dual, so is every one of its parts. The entire system of things gets represented in every particle. There is somewhat that resembles the ebb and flow of the sea, day and night, man and woman, in a single needle of the pine, in a kernel of corn, in each individual of every animal tribe. The reaction, so grand in the elements, is repeated within these small boundaries. For example, in the animal kingdom the physiologist has observed that no creatures are favorites, but a certain compensation balances every gift and every defect. A surplusage given to one part is paid out of a reduction from another part of the same creature. If the head and neck are enlarged, the trunk and extremities are cut short.
The theory of the mechanic forces is another example. What we gain in power is lost in time, and the converse. The periodic or compensating errors of the planets is another instance. The influences of climate and soil in political history are another. The cold climate invigorates. The barren soil does not breed fevers, crocodiles, tigers or scorpions.
The same dualism underlies the nature and condition of man. Every excess causes a defect; every defect an excess. Every sweet hath its sour; every evil its good. Every faculty which is a receiver of pleasure has an equal penalty put on its abuse. It is to answer for its moderation with its life. For every grain of wit there is a grain of folly. For everything you have missed, you have gained something else; and for everything you gain, you lose something. If riches increase, they are increased that use them. If the gatherer gathers too much, Nature takes out of the man what she puts into his chest; swells the estate, but kills the owner. Nature hates
