In no sense other than an utterly trivial one is reproduction the inverse of chemical disintegration. It is a misunderstanding of genetics to suppose that reproduction is only 'intended' to make facsimiles, for parasexual processes of genetical exchange are to be found in the simplest living things.

Asexual reproduction by females, parthenogenesis, is not only possible but it still occurs here and there in the modern world, pernaps as an atavistic survival of the once only means of reproduction in an all female world.

 
Elizabeth Gould Davis
 

An original is a creation motivated by desire.
Any reproduction of an original is motivated by necessity.
The original is the result of an automatic process, the reproduction, of a mechanical process. In other words: Inspiration then information; each validates the other.
All other considerations are beyond the scope of these statements.
It is marvelous that we are the only species that creates gratuitous forms. To create is divine, to reproduce is human.

 
Man Ray
 

Art alone makes life possible – this is how radically I should like to formulate it. I would say that without art man is inconceivable in physiological terms.. ..I would say man does not consist only of chemical processes, but also of metaphysical occurrences. The provocateur of the chemical processes is located outside the world. Man is only truly alive when he realizes he is a creative, artistic being.. ..Even the act of peeling a potato can be a work of art if it is a conscious act.

 
Joseph Beuys
 

The chief function of the city is to convert power into form, energy into culture, dead matter into the living symbols of art, biological reproduction into social creativity.

 
Lewis Mumford
 

[G]enes make enzymes, and enzymes control the rates of chemical processes. Genes do not make “novelty seeking” or any other complex and overt behavior. Predisposition via a long chain of complex chemical reactions, mediated through a more complex series of life's circumstances, does not equal identification or even causation.
