#adaptation

As natural selection acts by competition, it adapts the inhabitants of each country only in relation to the degree of perfection of their associates; so that we need feel no surprise at the inhabitants of any one country, although on the ordinary view supposed to have been specially created and adapted for that country, being beaten and supplanted by the naturalised productions from another land. ↗

Suicide is a form of murder— premeditated murder. It isn’t something you do the first time you think of doing it. It takes some getting used to. And you need the means, the opportunity, the motive. A successful suicide demands good organization and a cool head, both of which are usually incompatible with the suicidal state of mind. It’s important to cultivate detachment. One way to do this is to practice imagining yourself dead, or in the process of dying. If there’s a window, you must imagine your body falling out the window. If there’s a knife, you must imagine the knife piercing your skin. If there’s a train coming, you must imagine your torso flattened under its wheels. These exercises are necessary to achieving the proper distance. The debate was wearing me out. Once you've posed that question, it won't go away. I think many people kill themselves simply to stop the debate about whether they will or they won't. Anything I thought or did was immediately drawn into the debate. Made a stupid remark—why not kill myself? Missed the bus—better put an end to it all. Even the good got in there. I liked that movie—maybe I shouldn’t kill myself. In reality, it was only part of myself I wanted to kill: the part that wanted to kill herself, that dragged me into the suicide debate and made every window, kitchen implement, and subway station a rehearsal for tragedy. ↗

Remember that in every single case in history the process of adaptation has been one of exceeding slowness. Do not look for the impossible, but do not let your path deviate from the quiet and steadfast insistence on full opportunities for your powers. ↗

In all works on Natural History, we constantly find details of the marvellous adaptation of animals to their food, their habits, and the localities in which they are found. ↗

It is a law of nature we overlook, that intellectual versatility is the compensation for change, danger, and trouble. An animal perfectly in harmony with its environment is a perfect mechanism. Nature never appeals to intelligence until habit and instinct are useless. There is no intelligence where there is no change and no need of change. Only those animals partake of intelligence that have a huge variety of needs and dangers. ↗

— H.G. Wells
