26. Natural Theory / A. Speculations on Nature / 1. Nature
'Nature' refers to two things - form and matter [Aristotle]
Nothing natural is disorderly, because nature is responsible for all order [Aristotle]
Why are some things destructible and others not? [Aristotle]
Nature does nothing in vain [Aristotle]
The principle of determination in things obtains the greatest effect with the least effort [Leibniz]
Nature is a principle of change, so we must understand change first [Aristotle]
26. Natural Theory / A. Speculations on Nature / 2. Natural Purpose / a. Final purpose
There has to be some goal, and not just movement to infinity [Aristotle]
Nature has purpose, and aims at what is better. Is it coincidence that crops grow when it rains? [Aristotle]
If nature makes everything for a purpose, then plants and animals must have been made for man [Aristotle]
Everything is arranged around a single purpose [Aristotle]
An unworn sandal is in vain, but nothing in nature is in vain [Aristotle]
26. Natural Theory / A. Speculations on Nature / 2. Natural Purpose / b. Limited purposes
The nature of a thing is its end and purpose [Aristotle]
Teeth and crops are predictable, so they cannot be mere chance, but must have a purpose [Aristotle]
Aristotle needed to distinguish teleological description from teleological explanation [Irwin on Aristotle]
The nature of any given thing is determined by its end [Aristotle]
The best instruments have one purpose, not many [Aristotle]
It is folly not to order one's life around some end [Aristotle]
A machine is best defined by its final cause, which explains the roles of the parts [Leibniz]
A thing's purpose is ambiguous, and from one point of view we ourselves are ends [Aristotle]
26. Natural Theory / A. Speculations on Nature / 2. Natural Purpose / c. Purpose denied
Eyes could be used for a natural purpose, or for unnatural seeing, or for a non-seeing activity [Aristotle]
26. Natural Theory / A. Speculations on Nature / 3. Natural Function
Is ceasing-to-be unnatural if it happens by force, and natural otherwise? [Aristotle]
Each thing's function is its end [Aristotle]
26. Natural Theory / A. Speculations on Nature / 4. Mathematical Nature
Minds unconsciously count vibration beats in music, and enjoy it when they coincide [Leibniz]
Pythagoreans say the whole universe is made of numbers [Aristotle]
26. Natural Theory / A. Speculations on Nature / 5. Infinite in Nature
Continuity depends on infinity, because the continuous is infinitely divisible [Aristotle]
The heavens seem to be infinite, because we cannot imagine their end [Aristotle]
There are potential infinities (never running out), but actual infinity is incoherent [Aristotle, by Friend]
26. Natural Theory / A. Speculations on Nature / 6. Early Matter Theories / a. Greek matter
Matter is neither a particular thing nor a member of a determinate category [Aristotle]
Aristotle says matter is a lesser substance, rather than wholly denying that it is a substance [Aristotle, by Kung]
Matter is perceptible (like bronze) or intelligible (like mathematical objects) [Aristotle]
Substance must exist, because something must endure during change between opposites [Aristotle]
Aristotle had a hierarchical conception of matter [Aristotle, by Fine,K]
Matter desires form, as female desires male, and ugliness desires beauty [Aristotle]
Matter is the limit of points and lines, and must always have quality and form [Aristotle]
The primary matter is the substratum for the contraries like hot and cold [Aristotle]
Aristotle's matter can become any other kind of matter [Aristotle, by Wiggins]
26. Natural Theory / A. Speculations on Nature / 6. Early Matter Theories / b. Prime matter
Primary matter is what characterises other stuffs, and it has no distinct identity [Aristotle]
Ultimate matter is discredited, as Aristotle merged substratum of change with bearer of properties [Simons on Aristotle]
Aristotle may only have believed in prime matter because his elements were immutable [Aristotle, by Alexander,P]
The traditional view of Aristotle is God (actual form) at top and prime matter (potential matter) at bottom [Aristotle, by Gill,ML]
Prime matter is nothing when it is at rest [Leibniz]
26. Natural Theory / A. Speculations on Nature / 6. Early Matter Theories / c. Ultimate substances
There couldn't be just one element, which was both water and air at the same time [Aristotle]
26. Natural Theory / A. Speculations on Nature / 6. Early Matter Theories / e. The One
It doesn't explain the world to say it was originally all one. How did it acquire diversity? [Aristotle]
26. Natural Theory / A. Speculations on Nature / 6. Early Matter Theories / f. Ancient elements
When Aristotle's elements compound they are stable, so why would they ever separate? [Weisberg/Needham/Hendry on Aristotle]
Aether moves in circles and is imperishable; the four elements perish, and move in straight lines [Aristotle, by Gill,ML]
An element is what bodies are analysed into, and won't itself divide into something else [Aristotle]
The Four Elements must change into one another, or else alteration is impossible [Aristotle]
Fire is hot and dry; Air is hot and moist; Water is cold and moist; Earth is cold and dry [Aristotle]
I claim that Aristotle's foundation is the four elements, and not wholly potential prime matter [Aristotle, by Gill,ML]
The true elements are atomic monads [Leibniz]
26. Natural Theory / A. Speculations on Nature / 6. Early Matter Theories / g. Atomism
Bodies are endlessly divisible [Aristotle]
I think the corpuscular theory, rather than forms or qualities, best explains particular phenomena [Leibniz]
Leibniz rejected atoms, because they must be elastic, and hence have parts [Leibniz, by Garber]
Atomism is irrational because it suggests that two atoms can be indistinguishable [Leibniz]
Microscopes and the continuum suggest that matter is endlessly divisible [Leibniz]
There are atoms of substance, but no atoms of bulk or extension [Leibniz]
Things are infinitely subdivisible and contain new worlds, which atoms would make impossible [Leibniz]
The only simple things are monads, with no parts or extension [Leibniz]
Wood is potentially divided through and through, so what is there in the wood besides the division? [Aristotle]
If a body is endlessly divided, is it reduced to nothing - then reassembled from nothing? [Aristotle]
26. Natural Theory / A. Speculations on Nature / 7. Later Matter Theories / a. Early Modern matter
Leibniz struggled to reconcile bodies with a reality of purely soul-like entities [Jolley on Leibniz]
Secondary matter is active and complete; primary matter is passive and incomplete [Leibniz]
Not all of matter is animated, any more than a pond full of living fish is animated [Leibniz]
Every particle of matter contains organic bodies [Leibniz]
Bare or primary matter is passive; it is clothed or secondary matter which contains action [Leibniz]
26. Natural Theory / A. Speculations on Nature / 7. Later Matter Theories / c. Matter as extension
Even if extension is impenetrable, this still offers no explanation for motion and its laws [Leibniz]
Leibniz eventually said resistance, rather than extension, was the essence of body [Leibniz, by Pasnau]
