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.
Take this at least, this last advice, my son:
Keep a stiff rein, and move but gently on:
The coursers of themselves will run too fast,
Your art must be to moderate their haste.
