Interesting philosophers hardly every give you explicitly valid arguments [Martin,M]
|
|
Full Idea:
Notice that very few philosophers - certainly almost none of the ones who are interesting to read - give you explicitly valid arguments.
|
|
From:
Michael Martin (Interview with Baggini and Stangroom [2001], p.134)
|
|
A reaction:
I never thought that was going to happen in philosophy. What I do get is, firstly, lots of interesting reasons for holding beliefs, and a conviction that good beliefs need good reasons, and, secondly, a really coherent view of the world.

Valid arguments can be rejected by challenging the premises or presuppositions [Martin,M]
|
|
Full Idea:
Putting forward a valid argument isn't necessarily going to succeed in getting someone to see things your way, because if they don't accept the conclusion, they ask which premises they should reject, or whether an illegitimate assumption is being made.
|
|
From:
Michael Martin (Interview with Baggini and Stangroom [2001], p.136)
|
|
A reaction:
Valid arguments are still vital. It is just that good philosophers realise the problem noted here, and spend huge stretches of discussion on establishing acceptance of premises, and showing that there are no dodgy presuppositions.

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.

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.

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.

Types are properties, and tokens are events. Are they split between mental and physical, or not? [Sturgeon]
|
|
Full Idea:
The question is whether mental and physical types (which are properties) are distinct, and whether mental and physical tokens (which are events) are distinct.
|
|
From:
Scott Sturgeon (Matters of Mind [2000], Intro)
|
|
A reaction:
Helpful. While the first one gives us the rather dodgy notion of 'property dualism', the second one seems to imply Cartesian dualism, if the events really are distinct. It seems to me that thought is an aspect of brain events, not a distinct event.

The main argument for physicalism is its simple account of causation [Sturgeon]
|
|
Full Idea:
The dominant empirical argument for physicalism is the Overdetermination Argument: physics is closed and complete, mind is causally efficacious, the world isn't choc-full of overdetermination, so the mind is physical as well.
|
|
From:
Scott Sturgeon (Matters of Mind [2000], Intro)
|
|
A reaction:
I find this argument utterly convincing. The idea that there is only one thing which is outside the interconnected causal nexus which seems to constitute the rest of reality, and that is a piece of meat inside our heads, strikes me as totally ridiculous.

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.
