There is one living spirit prevalent over this world, (subject to certain contingencies of organic matter & chiefly heat), which assumes a multitude of forms each having acting principle according to subordinate laws. — There is one thinking sensible principle (intimately allied to one kind of organic matter—have & which thinking principle seems to be given a assumed according to a more extended relations of the individuals, whereby choice with memory or reason? is necessary—which is modified into endless forms bearing a close relation in degree & kind to the endless forms of the living beings.

Owing to this struggle for life, any variation, however slight and from whatever cause proceeding, if it be in any degree profitable to an individual of any species, in its infinitely complex relations to other organic beings and to external nature, will tend to the preservation of that individual, and will generally be inherited by its offspring. The offspring, also, will thus have a better chance of surviving, for, of the many individuals of any species which are periodically born, but a small number can survive. I have called this principle, by which each slight variation, if useful, is preserved, by the term of Natural Selection, in order to mark its relation to man's power of selection.

It’s not a matter of old or new forms; a person writes without thinking about any forms, he writes because it flows freely from his soul.

 

Anton Chekhov

 

Under Aristotle the "Reader," whose knowledge of Trojan areté seems conspicuously absent, forms and substances dominate all. The Good is a relatively minor branch of knowledge called ethics; reason, logic, knowledge are his primary concerns. Areté is dead and science, logic and the University as we know it today have been given their founding charter: to find and invent an endless proliferation of forms about the substantive elements of the world and call these forms knowledge, and transmit these forms to future generations. As "the system."

Consider what kind of authority [can be ascribed to] any principle which it open to us to choose to regard as authoritative or not. I may choose for example to observe a regimen of asceticism and fasting ... for reasons of health ... What authority such principles possess derives from the reasons for my choice. Insofar as they are good reasons, the principles have corresponding authority; insofar as they are not, the principles are to that same extent deprived of authority. It would follow that a principle for the choice of which no reasons could be given would be a principle devoid of authority. I might indeed adopt such a principle from whim or caprice or from some arbitrary purpose ... but if I then chose to abandon the principle whenever it suited me, I would be entirely free to do so.

 

Alasdair MacIntyre

 

The blindness of those who think it absurd to suppose that complex organic forms may have arisen by successive modifications out of simple ones becomes astonishing when we remember that complex organic forms are daily being thus produced. A tree differs from a seed immeasurably in every respect... Yet is the one changed in the course of a few years into the other: changed so gradually, that at no moment can it be said—Now the seed ceases to be, and the tree exists.
