The recoil from the absolute of mechanism was into an equally sterile absolute of the organic: the raw primitive. The organic processes, reduced to shadows by the machine, made a violent effort to retrieve their position. The machine, which acerbically denied the flesh, was offset by the flesh, which denied the rational, the intelligent, the orderly processes of behavior that have entered into all man’s cultural developments—even those developments that most closely derive from the organic. The spurious notion that mechanism had naught to learn from life was supplanted by the equally false notion that life had nothing to learn from mechanism.

 
Lewis Mumford
 

[Biology has] become the paramount science, exceeding other disciplines, including physics and chemistry at least, in the creative tumult of its disciplines and disputations. [...] I'll also be so bold at this point to suggest that we are now at the edge of establishing the two fundamental laws of biology: The first law is that all of the phenomena of biology, the entities and the processes, are ultimately obedient to the laws of physics and chemistry. Not immediately reducible to them, but ultimately consistent and in consilience with them, by a cause and effect explanation. The second law is that all biological phenomena, these entities and processes that define life itself, have arisen by evolution through natural selection.

 
E. O. Wilson
 

In the spiritual life, as in all organic processes, everyone has their optimum and it is just as harmful to go beyond it as not to attain it.

 
Pierre Teilhard de Chardin
 

We need, in a special way, to work twice as hard to make all people understand that animals are fellow creatures, that we must protect them and love them as we love ourselves... The basis for peace is respecting all creatures... That's the basis, the beginning for peace. ...We know we cannot defend or be kind to animals until we stop exploiting them - exploiting them in the name of science, exploiting animals in the name of sport, exploiting animals in the name of fashion, and yes, exploiting animals in the name of food.

 
Cesar Chavez
 

Nevertheless, this individual aspect [just-so-ness] of number appears to contain the mysterious factor that enables it to organize psyche and matter jointly.
