My reading shows a lot of different, sometimes contrasting, ideas about first and second nature.
When we say “second nature” colloquially, it suggests natural or inborn talent. It suggests an unconscious ability without thought.
Another view is that “first nature” is the natural world with no human intervention. An example is the physics of a distant star; there is no human effect on this aspect of nature. “Second nature” is anything that is transformed by by human thought. This is a modern re-interpretation of the terms, and I don’t like them. Too academic and postmodern for me.
The most egregious example of postmodern re-interpretation is this description of “third nature”: *Third nature or appearing consists of the global dispersal of mediated specular image flows through such spaces as television program texts, Internet web sites and virtual reality simulations. Third nature, which has assumed an increasing importance within the postindustrial world over the last twenty years, deterritorialises us from immediate face to face contact characteristic of first nature, and wires us into an interconnected global stratosphere. * Puh-leeeze.
Older concepts are more interesting.
First nature is seen as evil or animalistic, similar to the concept of “original sin.” By this definition we are all born with first nature (original sin from Adam and Eve), and must learn to acquire virtue, or second nature.
On the other hand, consider this quote from the play “Rule of the Bone” by Russell Banks wherein first nature is some zen awareness of the present moment: *
But life is short I guess and you have to celebrate it when you can…
-“No plans, no regrets”, he said, “Praise an’ thanks mus’ be sufficient unto ev’ry day”.
-I said, “Yeah but it’d be hard to do that the rest of my life. Making plans and having regrets, man, they’re like second nature to me”.
-“Y’ first nature, dat be what you got to come to mon”, he explained.*
Then there is the Aristotelian notion that second nature is created by habit – through repetition the learning becomes automatic. The I Ching also suggests this in hexagram 21 (Wilhelm/Baynes version) “through repetition, the [student’s] material becomes his own”
