Essential definitions show the differences that discriminate things, and make them what they are [Boyle]
|
|
Full Idea:
Essential definitions are such as are taken from the essential differences of things, which constitute them in such a sort of natural bodies, and discriminate them from all those of any other sort.
|
|
From:
Robert Boyle (The Origin of Forms and Qualities [1666], p.41?), quoted by Peter Alexander - Ideas, Qualities and Corpuscles
|
|
A reaction:
I don't think this goes as far as the aim Aristotle had in definitions, which was more than merely to 'discriminate' each thing. A full definition explains the thing as well.

Boyle attacked a contemporary belief that powers were occult things [Boyle, by Alexander,P]
|
|
Full Idea:
Boyle attacks an idea of powers, held by some modern schoolmen and chemists, that makes powers occult.
|
|
From:
report of Robert Boyle (The Origin of Forms and Qualities [1666]) by Peter Alexander - Ideas, Qualities and Corpuscles 03.3
|
|
A reaction:
[This involves Boyle's famous example of a key having the power to turn a lock] On p.86 Alexander says the 'occult' belief is in affinities, antipathies, attractions and repulsions. How did Boyle explain magnetism?

Form is not a separate substance, but just the manner, modification or 'stamp' of matter [Boyle]
|
|
Full Idea:
I understand the word 'form' to mean, not a real substance distinct from matter, but only the matter itself of a natural body, with its peculiar manner of existence [corpuscular structure], which may be called its 'essential modification' or 'stamp'.
|
|
From:
Robert Boyle (The Origin of Forms and Qualities [1666], p.324), quoted by Jan-Erik Jones - Real Essence §3
|
|
A reaction:
I don't think Aristotle ever thought that a form was separate from its matter, let alone qualifying as a substance. On the whole, Boyle attacks scholastic philosophy, rather than Aristotle.
|
|
15953
|
To cite a substantial form tells us what produced the effect, but not how it did it [Boyle]
|
|
Full Idea:
If it be demanded why rhubarb purges choler, snow dazzles the eyes rather than grass etc., that these effects are performed by substantial forms of the respective bodies is at best but to tell me what is the agent, not how the effect is wrought.
|
|
From:
Robert Boyle (The Origin of Forms and Qualities [1666], p.47?), quoted by Peter Alexander - Ideas, Qualities and Corpuscles 01.2
|
|
A reaction:
This is the problem of the 'virtus dormitiva' of opium (which at least tells you it was the opium what done it). I take Aristotle to have aspired to a lot more than this. He wanted a full definition, which would contain lots of information about the form.

Boyle's term 'texture' is not something you feel, but is unobservable structures of particles [Boyle, by Alexander,P]
|
|
Full Idea:
Perhaps Boyle's most important technical terms is 'texture'. ...It must not be confused with the way we feel the texture of a surface like sandpaper or velvet; it is rather a structure of unobservable particles and so it is not directly observable.
|
|
From:
report of Robert Boyle (The Origin of Forms and Qualities [1666]) by Peter Alexander - Ideas, Qualities and Corpuscles 03.2
|
|
A reaction:
This is the basis for Alexander's reassessment of what Boyle and Locke meant by a 'secondary quality', which, he says, is a physical feature of objects, not a mental experience.
|

|
Explanation is generally to deduce it from something better known, which comes in degrees [Boyle]
|
|
Full Idea:
Generally speaking, to render a reason of an effect or phenomenon is to deduce it from something else in nature more known than itself, and consequently there may be diverse kinds of degrees of explication of the same thing.
|
|
From:
Robert Boyle (Certain Physical Essays [1672], II:21), quoted by Robert Pasnau - Metaphysical Themes 1274-1671 23.4
|
|
A reaction:
There is a picture of a real explanatory structure to nature, from which we pick bits that interest us for entirely pragmatic reasons. Boyle and I are as one on this matter.
|
|
16737
|
The best explanations get down to primary basics, but others go less deep [Boyle]
|
|
Full Idea:
Explications be most satisfactory that show how the effect is produced by the more primitive affects of matter (bulk, shape and motion) but are not to be despised that deduce them from more familiar qualities such as heat, weight, fluidity, fermentation.
|
|
From:
Robert Boyle (Certain Physical Essays [1672], II:22), quoted by Robert Pasnau - Metaphysical Themes 1274-1671 23.4
|
|
A reaction:
[Compressed, and continued from Idea 16736] So there is a causal structure, and the best explanations go to the bottom of it, but lesser explanations only go half way down. So a very skimpy explanation ('dormative power') is still an explanation.

Prescriptivism says 'ought' without commitment to act is insincere, or weakly used [Hooker,B]
|
|
Full Idea:
Prescriptivism holds that if you think one 'ought' to do a certain kind of act, and yet you are not committed to doing that act in the relevant circumstances, then you either spoke insincerely, or are using the word 'ought' in a weak sense.
|
|
From:
Brad W. Hooker (Prescriptivism [1995], p.640)
|
|
A reaction:
So that's an 'ought', but not a 'genuine ought', then? (No True Scotsman move). Someone ought to rescue that drowning child, but I can't be bothered.

Modern utilitarians value knowledge, friendship, autonomy, and achievement, as well as pleasure [Hooker,B]
|
|
Full Idea:
Most utilitarians now think that pleasure, even if construed widely, is not the only thing desirable in itself. ...Goods also include important knowledge, friendship, autonomy, achievement and so on.
|
|
From:
Brad W. Hooker (Rule Utilitarianism and Euthanasia [1997], 2)
|
|
A reaction:
That pleasure is desired is empirically verifiable, which certainly motivated Bentham. A string of other desirables each needs to be justified - but how? What would be the value of a 'friendship' if neither party got pleasure from it?
|
|

Euthanasia is active or passive, and voluntary, non-voluntary or involuntary [Hooker,B]
|
|
Full Idea:
Six types of euthanasia: 1) Active voluntary (knowing my wishes), 2) Active non-voluntary (not knowing my wishes), 3) Active involuntary (against my wishes), 4) Passive voluntary, 5) Passive non-voluntary, 6) Passive involuntary.
|
|
From:
Brad W. Hooker (Rule Utilitarianism and Euthanasia [1997], 5)
|
|
A reaction:
'Active' is intervening, and 'passive' is not intervening. A helpful framework.
|
|

Euthanasia may not involve killing, so it is 'killing or not saving, out of concern for that person' [Hooker,B]
|
|
Full Idea:
Passive euthanasia is arguably not killing, and the death involved is often painful, so let us take the term 'euthanasia' to mean 'either killing or passing up opportunities to save someone, out of concern for that person'.
|
|
From:
Brad W. Hooker (Rule Utilitarianism and Euthanasia [1997], 1)
|
|
A reaction:
This sounds good, and easily settled, until you think concern for that person could have two different outcomes, depending on whether the criteria are those of the decider or of the patient. Think of religious decider and atheist patient, or vice versa.

The corpuscles just have shape, size and motion, which explains things without 'sympathies' or 'forces' [Boyle, by Alexander,P]
|
|
Full Idea:
In Boyle's corpuscular philosophy, all material substances are composed of minute particles or corpuscles, with ordinary properties such as shape, size and motion. There was no need for occult relations between them, such as sympathies, or even forces.

Space alone, and time alone, will fade away, and only their union has an independent reality [Minkowski]
|
|
Full Idea:
Henceforth, space by itself, and time by itself, are doomed to fade away into mere shadows, and only a kind of union of the two will preserve an independent reality.
|
|
From:
Hermann Minkowski (Space and Time [1908], Intro)
|
|
A reaction:
Notice the qualification that it is a 'kind of' union. Deep confusion arises from exaggerating the analogy between space and time. Craig Bourne remarks (2006:157) that this shows independence of measurement, not of reality
|
|

|
I don't see how mere moving matter can lead to the bodies of men and animals, and especially their seeds [Boyle]
|
|
Full Idea:
I confess I cannot well conceive how from matter, barely put into motion and left to itself, there could emerge such curious fabricks as the bodies of men and perfect animals, and more admirably contrived parcels of matter, as seeds of living creatures.
|
|
From:
Robert Boyle (The Sceptical Chemist [1661], p.569), quoted by Peter Alexander - Ideas, Qualities and Corpuscles
|
|
A reaction:
This is here to show that one of the most brilliant intellects of the seventeenth century thought carefully about this question and couldn't answer it. Natural selection really was a rather clever idea.
