Involution

Involution and Evolution are two rules of arithmetic which signify getting in  and getting out . Involution signifies such matters as getting in love, getting into a lawsuit, or getting into debt. It is the rule of entanglement, and is represented by a fly in a spider's web.

Evolution comprehends all the tricks, shifts, schemes, and stratagems, by which we get out of our various difficulties; but it may be observed that it is much easier to become involved in any matter, than to get disentangled: whatever may be our evolutions, it is a difficult matter to get out of love, out of a law-suit, or out of debt.
