Ever encountered Zen and the Art of Motorcycle Maintenance by any chance? This question is at the centre of that book. — Wayfarer
As luck would have it, I'm currently reading that exact book - I'm on the 30th chapter and, to be honest, I find the book a challenging read. Anyway, below is what the Wikipedia page on
Quality (philosophy) has to say about Robert M. Pirsig's book Zen and the Art of Motorcycle Maintenance:
In his book, Zen and the Art of Motorcycle Maintenance, Robert M. Pirsig examines concepts of quality in classical and romantic, seeking a Metaphysics of Quality and a reconciliation of those views in terms of non-dualistic holism. — Wikipedia
The key concept (non-dualistic holism) in Pirsig's book has been underlined for your convenience. Take the dualistic notion that lies at the very foundation of all life, to wit hot vs cold: it's said that life found a home on this watery-rocky planet we call earth for the simple reason that it's neither too hot nor too cold thus allowing life-giving and life-sustaining liquid water to exist.
Take a closer look at what hot and cold are. From a dualistic point of view, they're distinct from each other - opposites, yin and yang as it were - but physics (science), the paradigmatic case of the mathematization of the universe, unites these two dualistically distinct
qualities under one banner viz.
temperature. What our ancient forefathers thought were
two separate
qualities (hot vs cold) turns out to be simply variations in
one same
quantity (temperature).
Given the above, it would seem that Pirsig would've made a convincing case for
non-dualistic holism had he resorted to mathematics i.e. he should've chosen
quantity over
quality to make his case.
Quantity directly relates to mass, Quality relates to the components that make up a mass. — Peter Paapaa
I was turning the matter over in my mind when it dawned on me that unlike colors which are simply different wavelengths of light, there are some aspects of human experience that can't be explained in terms of quantity. Take for example the emotions of love and anger; the former is modulated by oxytocin while the latter by adrenaline. These two emotions are effects of
two different biomolecules, the difference between these biomolecules irreducible to mere variations in quantity. In other words, love and anger are qualitatively different; however, the intensity of these emotions probably are just a matter of the concentration (
quantity) of the respective biomolecules. All this under the assumption that biochemists and physiologists are correct of course.
Perhaps if we dig a little deeper and get down to the level of quarks, even emotions can be translated into
quantity - the number/mass of quarks in a given biomolecule. I wonder if biochemists and physiologists have ever thought along these lines. Gestalt? Possibly. At this point I'm taking a tentative step outside the borders what is known to science (and me).
There is, obviously, such a thing as quality. Why deny the obvious? But to my mind, the qualitative has always been a matter of judgement. A subjective factor that relates to the purposes I intend for the object.
For example; there are two loaves of bread in my fridge. One is stale and the other is fresh. Which is the better quality? If I want to make a sandwich - the fresh bread is better quality. But if I want to make bread and butter pudding, the stale bread is better. (And it really is - stale bread will retain its structure, whereas fresh bread turns to mush.)
The quality of the object is not inherent to the object, but to the suitability of the object for my purposes - and is therefore, a matter of judgement. It's like Zen and the Art of Motorcycle Maintenance, a terrible book, but just the right thickness to level my bookshelf. In that regard, it's the best book I've got. — counterpunch
To construct an item with structural integrity, an engineer must first consider a material’s mechanical properties, such as toughness, strength, weight, hardness, and elasticity, and then determine the size and shape necessary for the material to withstand the desired load for a long life — Wikipedia
All the characteristics (underlined) that define
structural integrity are
quantities.
Too
judgment requires
quantification to determine whether
better or
worse for "...purposes..."
Reality consists of relations and non-relations. Quantity is a type of relation and quality might refer to non-relations. Ontic structural realism says that there are only relations - relations between relations between relations etc. I think it's ok for there to be relations between relations but relations would be undefined if they were ultimately not grounded in non-relations. Relations and non-relations are inseparable, so it's no wonder that a quality like color is related to a relation like the wavelength of electromagnetic waves. — litewave
Name a
quality that can't be/hasn't been viewed as a relation. Nothing springs to mind. I'm approaching the matter from the position that once a relation is in place,
quantity automatically enters the picture
I think that quality is a concept which extends into all areas not just maths. However, I think that it goes beyond beauty. This can be superficial and quality is about depth as well. The most obvious example that comes to my mind is if someone wrote a philosophy book, written in the most exquisite language but lacking in sufficient knowledge would it have quality? Certainly,I would see it as rather lacking.
Obviously, the idea of quality has some kind of subjective criteria. For instance, certain literature is viewed as literary fiction. I know many people who find this fiction rather pretentious. I have mixed feelings and read some of this but can see that it is not necessarily of better quality than some fiction which is not ranked as literary fiction. So, I would say that the whole idea of quality is about certain standards, which are socially constructed. — Jack Cummins
I'm going to focus my reply on
subjectivity. Both you and
@counterpunch have raised the same point. Do you have any good reasons to come to the conclusion that
subjectivity somehow
isn't quantifiable? Name something which you think is
subjective and
non-quantifiable (can't be translated into numbers (arithmetic) or shapes (geometry)].
