A Reaction

To 'show how' something happens needs a bit of precisification. It is probably analytic that 'showing how' means 'revealing the mechanism', though 'mechanism' then becomes the tricky concept.


The 13 ideas from 'Thinking About Mechanisms'

Mechanisms are not just push-pull systems [Machamer/Darden/Craver]
Mechanisms are systems organised to produce regular change [Machamer/Darden/Craver]
A mechanism explains a phenomenon by showing how it was produced [Machamer/Darden/Craver]
Our account of mechanism combines both entities and activities [Machamer/Darden/Craver]
Activities have place, rate, duration, entities, properties, modes, direction, polarity, energy and range [Machamer/Darden/Craver]
Functions are not properties of objects, they are activities contributing to mechanisms [Machamer/Darden/Craver]
Penicillin causes nothing; the cause is what penicillin does [Machamer/Darden/Craver]
Laws of nature have very little application in biology [Machamer/Darden/Craver]
Descriptions of explanatory mechanisms have a bottom level, where going further is irrelevant [Machamer/Darden/Craver]
We can abstract by taking an exemplary case and ignoring the detail [Machamer/Darden/Craver]
The explanation is not the regularity, but the activity sustaining it [Machamer/Darden/Craver]
There are four types of bottom-level activities which will explain phenomena [Machamer/Darden/Craver]
We understand something by presenting its low-level entities and activities [Machamer/Darden/Craver]
