Only Kant and Hegel have united nature, morals, politics, aesthetics and religion [Gardner]
|
|
Full Idea:
Apart from Hegel, no later philosophical system equals in stature Kant's attempt to weld together the diverse fields of natural science, morality, politics, aesthetics and religion into a systematic overarching epistemological and metaphysical unity.
|
|
From:
Sebastian Gardner (Kant and the Critique of Pure Reason [1999], 10)
|
|
A reaction:
Earlier candidate are Plato and Aristotle. Earlier Enlightenment figures say little about morality or aesthetics. Hobbes ranges widely. Aquinas covered most things.

Modern geoemtry is either 'pure' (and formal), or 'applied' (and a posteriori) [Gardner]
|
|
Full Idea:
There is now 'pure' geometry, consisting of formal systems based on axioms for which truth is not claimed, and which are consequently not synthetic; and 'applied', a branch of physics, the truth of which is empirical, and therefore not a priori.
|
|
From:
Sebastian Gardner (Kant and the Critique of Pure Reason [1999], 03 'Maths')
|
|
A reaction:
His point is that there is no longer any room for a priori geometry. Might the same division be asserted of arithmetic, or analysis, or set theory?

Activities have place, rate, duration, entities, properties, modes, direction, polarity, energy and range [Machamer/Darden/Craver]
|
|
Full Idea:
Activities can be identified spatiotemporally, and individuated by rate, duration, and types of entity and property that engage in them. They also have modes of operation, directionality, polarity, energy requirements and a range.
|
|
From:
Machamer,P/Darden,L/Craver,C (Thinking About Mechanisms [2000], 3)
|
|
A reaction:
This is their attempt at making 'activity' one of the two central concepts of ontology, along with 'entity'. A helpful analysis. It just seems to be one way of slicing the cake.

We understand something by presenting its low-level entities and activities [Machamer/Darden/Craver]
|
|
Full Idea:
The intelligibility of a phenomenon consists in the mechanisms being portrayed in terms of a field's bottom out entities and activities.
|
|
From:
Machamer,P/Darden,L/Craver,C (Thinking About Mechanisms [2000], 7)
|
|
A reaction:
In other words, we understand complex things by reducing them to things we do understand. It would, though, be illuminating to see a nest of interconnected activities, even if we understood none of them.

Heat and colour don't exist, so cannot mislead about the external world [Galileo, by Tuck]
|
|
Full Idea:
Galileo argued that there is no such thing as heat (and hence also as colour) in the external world, so there is no reason to conclude from colour-blindness that we cannot know the truth about the world.
|
|
From:
report of Galileo Galilei (Il Saggiatore ('The Assayer') [1623]) by Richard Tuck - Hobbes Ch.1
|
|
A reaction:
This key idea, taken up by Gassendi, Descartes and Locke, seems to me to be one of the most important (and, in retrospect, rather obvious) facts ever worked out by the human mind. Why does anyone still doubt it?

Tastes, odours and colours only reside in consciousness, and would disappear with creatures [Galileo]
|
|
Full Idea:
I think tastes, odours, colours, and so on are mere names as far as the objects are concerned, and only reside in consciousness. Hence if the living creature were removed, all these qualities would be wiped away and annihilated.
|
|
From:
Galileo Galilei (Il Saggiatore ('The Assayer') [1623]), quoted by Brian Ellis - The Philosophy of Nature: new essentialism Ch.3
|
|
A reaction:
A nice bold assertion of the primary/secondary distinction from the first great scientist. I agree, and to disagree (and hence side with Berkeley and Hume) is to head for metaphsical and epistemological confusion.

Functions are not properties of objects, they are activities contributing to mechanisms [Machamer/Darden/Craver]
|
|
Full Idea:
It is common to speak of functions as properties 'had by' entities, …but they should rather be understood in terms of the activities by virtue of which entities contribute to the workings of a mechanism.
|
|
From:
Machamer,P/Darden,L/Craver,C (Thinking About Mechanisms [2000], 3)
|
|
A reaction:
I'm certainly quite passionately in favour of cutting down on describing the world almost entirely in terms of entities which have properties. An 'activity', though, is a bit of an elusive concept.

Galileo introduced geometrico-mechanical explanation, based on Archimedes [Galileo, by Machamer/Darden/Craver]
|
|
Full Idea:
The modern idea of explaining with mechanisms became current in the 17th century when Galileo articulated a geometrico-mechanical form of explanation based on Archimedes' simple machines. This became the 'mechanical philosophy'.
|
|
From:
report of Galileo Galilei (Il Saggiatore ('The Assayer') [1623]) by Machamer,P/Darden,L/Craver,C - Thinking About Mechanisms 5.2
|
|
A reaction:
So is Archimedes the source? I would say that mechanical explanation is just commonsense, and is predominant in all human thinking, even in tiny infants.

Mechanisms are not just push-pull systems [Machamer/Darden/Craver]
|
|
Full Idea:
One should not think of mechanisms as exclusively mechanical (push-pull) systems.
|
|
From:
Machamer,P/Darden,L/Craver,C (Thinking About Mechanisms [2000], 1)
|
|
A reaction:
The difficulty seems to be that you could broaden the concept of 'mechanism' indefinitely, so that it covered history, mathematics, populations, cultural change, and even mathematics. Where to stop?
|
|

Our account of mechanism combines both entities and activities [Machamer/Darden/Craver]
|
|
Full Idea:
We emphasise the activities in mechanisms. This is explicitly dualist. Substantivalists speak of entities with dispositions to act. Process ontologists reify activities and try to reduce entities to processes. We try to capture both intuitions.
|
|
From:
Machamer,P/Darden,L/Craver,C (Thinking About Mechanisms [2000], 3)
|
|
A reaction:
[A quotation of selected fragments] The problem here seems to be the raising of an 'activity' to a central role in ontology, when it doesn't seem to be primitive, and will typically be analysed in a variety of ways.
|

Descriptions of explanatory mechanisms have a bottom level, where going further is irrelevant [Machamer/Darden/Craver]
|
|
Full Idea:
Nested hierachical descriptions of mechanisms typically bottom out in lowest level mechanisms. …Bottoming out is relative …the explanation comes to an end, and description of lower-level mechanisms would be irrelevant.
|
|
From:
Machamer,P/Darden,L/Craver,C (Thinking About Mechanisms [2000], 5.1)
|
|
A reaction:
This seems to me exactly the right story about mechanism, and it is a story I am associating with essentialism. The relevance is ties to understanding. The lower level is either fully understood, or totally baffling.
|
|

There are four types of bottom-level activities which will explain phenomena [Machamer/Darden/Craver]
|
|
Full Idea:
There are four bottom-out kinds of activities: geometrico-mechanical, electro-chemical, electro-magnetic and energetic. These are abstract means of production that can be fruitfully applied in particular cases to explain phenomena.
|
|
From:
Machamer,P/Darden,L/Craver,C (Thinking About Mechanisms [2000], 7)
|
|
A reaction:
I like that. It gives a nice core for a metaphysics for physicalists. I suspect that 'mechanical' can be reduced to something else, and that 'energetic' will disappear in the final story.

Aesthetic objectivists must explain pleasure being essential, but not in the object [Gardner]
|
|
Full Idea:
The aesthetic objectivist faces the difficulty of accounting for the fact that pleasure is not in the object, and is necessary for, and not just a contingent accompaniment to, aesthetic response.
|
|
From:
Sebastian Gardner (Aesthetics [1995], 1.2.3)
|
|
A reaction:
The objectivist has to claim, not utterly implausibly, that if you don't get pleasure from certain works, then you 'ought' to. You can ignore a good work, but to deny that it gives pleasure is a failing in you.

Laws of nature have very little application in biology [Machamer/Darden/Craver]
|
|
Full Idea:
The traditional notion of a law of nature has few, if any, applications in neurobiology or molecular biology.
|
|
From:
Machamer,P/Darden,L/Craver,C (Thinking About Mechanisms [2000], 3.2)
|
|
A reaction:
This is a simple and self-evident fact, and bad news for anyone who want to build their entire ontology around laws of nature. I take such a notion to be fairly empty, except as a convenient heuristic device.

Galileo mathematised movement, and revealed its invariable component - acceleration [Galileo, by Meillassoux]
|
|
Full Idea:
Galileo conceives of movement in mathematical terms. ...In doing so, he uncovered, beyond the variations of position and speed, the mathematical invariant of movement - that is to say, acceleration.
|
|
From:
report of Galileo Galilei (Two Chief World Systems [1632]) by Quentin Meillassoux - After Finitude; the necessity of contingency 5
|
|
A reaction:
That is a very nice advert for the mathematical physics which replaced the Aristotelian substantial forms. ...And yet, is acceleration some deep fact about nature, or a concept which is only needed if you insist on being mathematical?
