Cunning leads to knavery. It is but a step from one to the other, and that very slippery. Only lying makes the difference; add that to cunning, and it is knavery.
Nothing retains its form; new shapes from old. Nature, the great inventor, ceaselessly contrives. In all creation, be assured, there is no death - no death, but only change and innovation; what we men call birth is but a different new beginning; death is but to cease to be the same. Perhaps this may have moved to that, and that to this, yet still the sum of things remains the same.
