Everything in nature goes by law, and not by luck.
Even a superficial glance is sufficient to show that all the innumerable forms in which the life-urge of Nature manifests itself are subject to a fundamental law - one may call it an iron law of Nature - which compels the various species to keep within the definite limits of their own life-forms when propagating and multiplying their kind.
Nature's Laws are the invisible government of the earth.
We have to take care about nature as much as nature is taking care about us. Nature is very kind with us. And if you want to enjoy the gifts of nature and the promises of nature, we have to defer to nature and its needs, its rules, its norms.
If we knew all the laws of Nature, we should need only fact, or the description of one actual phenomenon, to infer all the particular results at that point.
We must respect the interior laws of creation, of this Earth, to learn these laws and obey them if we want to survive.
Nature is neither reasonable nor just. Nature is exact.
All life forms obey Nature's demands—except man, who has found ways of ignoring them.
Many have attempted unnatural acts, but Nature has always shown the way.
If a plant cannot live according to its nature, it dies; and so a man.
We gain our ends only with the laws of nature; we control her only by understanding her laws.
Nature is not benevolent; Nature is just, gives pound for pound, measure for measure, makes no exceptions, never tempers her decrees with mercy, or winks at any infringement of her laws.
In nature there are no rewards or punishments; there are consequences.
That very law which moulds a tear And bids it trickle from its source,- That law preserves the earth a sphere, And guides the planets in their course.
The notion that the natural world obeys its own rules and doesn't give a damn about your expectations comes as a massive shock. But the natural world is not so malleable. On the contrary, it will demand that you adapt to it - and if you don't, you die.
