26. Natural Theory / C. Causation / 3. Final causes

[Greek view of ultimate aim as the cause]

5 ideas
The four causes are the material, the form, the source, and the end [Aristotle]
     Full Idea: The first type of cause is that from which a thing is made (bronze of a statue); the second type is the form or pattern (ratio 2:1 for the octave); the third is the source (the deviser of a plan); the fourth type is the end (as health causes walking).
     From: Aristotle (Physics [c.337 BCE], 194b23-)
     A reaction: [Compressed quotation] These four became known as the Material Cause, the Formal Cause, the Efficient Cause, and the Final Cause. For a statue they are the bronze, the shape, the sculptor, and the beauty. We now focus on the Efficient Cause.
A final cause is simply a human desire [Spinoza]
     Full Idea: A cause which is called final is nothing else but human desire, in so far as it is considered as the origin or cause of anything.
     From: Baruch de Spinoza (The Ethics [1675], IV Pref)
     A reaction: A rather vicious swipe at Aristotle! It chimes in with the modern scientific view of the world (mostly associated with Hume), that nature has no intrinsic values or aims. On the large scale, Spinoza is right, but nature can still show us what has value.
Power rules in efficient causes, but wisdom rules in connecting them to final causes [Leibniz]
     Full Idea: In all of nature efficient causes correspond to final causes, because everything proceeds from a cause which is not only powerful, but wise; and with the rule of power through efficient causes, there is involved the rule of wisdom through final causes.
     From: Gottfried Leibniz (Metaphysical conseqs of principle of reason [1712], §5)
     A reaction: Nowadays this carrot-and-stick view of causation is unfashionable, but I won't rule it out. The deepest 'why?' we can ask won't just go away. This unity by a divine mind strikes me as too simple, but Leibniz is right to try to unify Aristotelian causes.
The idea of a final cause is very uncertain and unphilosophical [Hume]
     Full Idea: Your sense of 'natural' is founded on final causes, which is a consideration that appears to me pretty uncertain and unphilosophical.
     From: David Hume (Letters [1739], to Hutcheson 1739)
     A reaction: This is the rejection of Aristotelian teleology by modern science. I agree that the notion of utterly ultimate final cause is worse than 'uncertain' - it is an impossible concept. Nevertheless, I prefer Aristotle to Hume. Nature can teach us lessons.
We do not know the nature of one single causality [Nietzsche]
     Full Idea: We do not know the nature of one single causality.
     From: Friedrich Nietzsche (Unpublished Notebooks 1872-74 [1873], 19 [121])
