In the book of Physics, written by Aristotle. He talks about nature, cause and chance, teleology and necessity in nature. I was intrigued by the first two pages, where he talks about nature and form. In his introduction he talks about this idea, all natural objects being the substances. First let's talk about what he thinks to be the nature.
In the first paragraph Aristotle stated: " among thing that are, some are natural, others are due to other causes. Those that are natural are animal in their parts, plants in the simple bodies, such as earth, fire and water; for we say that these things and things of this sort are natural. All these things are evidently different from things not naturally constituted; for each of them has in itself an origin of change and stability, whether in place, or growth and decay or alteration".
When I think about it, what he says, make sense and i agree. I interpret it to be, things that when we human beings came on earth, we've seen many unexplainable things. Such as trees, animals etc. All these things we have no clue, on how they ended up being in this planet are consider to be natural. therefore nature are things we don't know the origin. He later says whatever has a nature is a substance. I think is right, for example: a substance is like a molecule in human body, without this molecule we wouldn't be human, and i think it's the same for nature. Without this substance there would'nt be nature according to Aristotle. Also he thinks that form is nature. I agree, because for something to be call nature, it needs a form or it has to have a form first, for example: a tree, would not be a tree if it didn't have the form. therefore according to Aristotle. so therefore the form plays an important role than the nature itself. The form precedes nature. that's why i believe he stated: " the form is nature more than the matter is ". Matter for Aristotle i think is what is actually is, for example: when we plant an apple tree, the result will be the same thing that was originally planted. According to Aristotle the apple is not the origin. It's being nothing more than what it really is.
