Classes, grouped by a convenient property, are logical constructions [Russell]
|
|
Full Idea:
Classes or series of particulars, collected together on account of some property which makes it convenient to be able to speak of them as wholes, are what I call logical constructions or symbolic fictions.
|
|
From:
Bertrand Russell (The Ultimate Constituents of Matter [1915], p.125)
|
|
A reaction:
When does a construction become 'logical' instead of arbitrary? What is it about a property that makes it 'convenient'? At this point Russell seems to have built his ontology on classes, and the edifice was crumbling, thanks to Wittgenstein.

If my body literally lost its mind, the object seen when I see a flash would still exist [Russell]
|
|
Full Idea:
My meaning may be made plainer by saying that if my body could remain in exactly the same state in which it is, though my mind had ceased to exist, precisely that object which I now see when I see a flash would exist, though I should not see it.
|
|
From:
Bertrand Russell (The Ultimate Constituents of Matter [1915], p.126)
|
|
A reaction:
Zombies, 70 years before Robert Kirk! Sense-data are physical. It is interesting to see a philosopher as committed to empiricism, anti-spiritualism and the priority of science as this, still presenting an essentially dualist picture of perception.

We have an apparent and a true self; only the second one exists, and we must seek to know it [Anon (Upan)]
|
|
Full Idea:
There are two selves, the apparent self, and the real Self. Of these it is the real Self (Atman), and he alone, who must be felt as truly existing. To the man who has felt him as truly existing he reveals his innermost nature.
|
|
From:
Anon (Upan) (The Upanishads [c.950 BCE], 'Katha')
|
|
A reaction:
A central Hindu doctrine against which Buddhism rebelled, by denying the self altogether. I prefer the Hindu view. A desire to abandon the self just seems to be a desire for death. Knowledge of our essential self is more interesting. But see Idea 2932!

A man is a succession of momentary men, bound by continuity and causation [Russell]
|
|
Full Idea:
The real man, I believe, however the police may swear to his identity, is really a series of momentary men, each different one from the other, and bound together, not by a numerical identity, but by continuity and certain instrinsic causal laws.
|
|
From:
Bertrand Russell (The Ultimate Constituents of Matter [1915], p.124)
|
|
A reaction:
This seems to be in the tradition of Locke and Parfit, and also follows the temporal-slices idea of physical objects. Personally I take a more physical view of things, and think the police are probably more reliable than Bertrand Russell.

We could probably, in principle, infer minds from brains, and brains from minds [Russell]
|
|
Full Idea:
It seems not improbable that if we had sufficient knowledge we could infer the state of a man's mind from the state of his brain, or the state of his brain from the state of his mind.
|
|
From:
Bertrand Russell (The Ultimate Constituents of Matter [1915], p.131)
|
|
A reaction:
This strikes me as being a very good summary of the claim that mind is reducible to brain, which is the essence of physicalism. Had he been born a little later, Russell would have taken a harder line with physicalism.

Without speech we cannot know right/wrong, true/false, good/bad, or pleasant/unpleasant [Anon (Upan)]
|
|
Full Idea:
If there were no speech, neither right nor wrong would be known, neither the true nor the false, neither the good nor the bad, neither the pleasant nor the unpleasant.
|
|
From:
Anon (Upan) (The Upanishads [c.950 BCE], 'Chandogya')
|
|
A reaction:
This could stand as the epigraph for the whole of modern philosophy of language. However, the text goes on to say that mind is higher than speech. The test question is the mental capabilities of animals. Do they 'know' pleasure, or truth?

By knowing one piece of clay or gold, you know all of clay or gold [Anon (Upan)]
|
|
Full Idea:
By knowing one lump of clay, all things made of clay are known; by knowing a nugget of gold, all things made of gold are known.
|
|
From:
Anon (Upan) (The Upanishads [c.950 BCE], 'Chandogya')
|
|
A reaction:
I can't think of a better basic definition of a natural kind. There is an inductive assumption, of course, which hits trouble when you meet fool's gold, or two different sorts of jade. But the concept of a natural kind is no more than this.

Six dimensions are needed for a particular, three within its own space, and three to locate that space [Russell]
|
|
Full Idea:
The world of particulars is a six-dimensional space, where six co-ordinates will be required to assign the position of any particular, three to assign its position in its own space, and three to assign the position of its space among the other spaces.
|
|
From:
Bertrand Russell (The Ultimate Constituents of Matter [1915], p.134)
|
|
A reaction:
Not a proposal that has caught on. One might connect the idea with the notion of 'frames of reference' in Einstein's Special Theory. Inside a frame of reference, three co-ordinates are needed; but where is the frame of reference?

Originally there must have been just Existence, which could not come from non-existence [Anon (Upan)]
|
|
Full Idea:
In the beginning there was Existence, One only, without a second. Some say that in the beginning there was non-existence only, and that out of that the universe was born. But how could such a thing be? How could existence be born of non-existence?
|
|
From:
Anon (Upan) (The Upanishads [c.950 BCE], 'Chandogya')
|
|
A reaction:
A very rare instance of an argument in the Upanishads, arising out of a disagreement. The monotheistic religions have preferred to make God the eternal element, presumably because that raises his status, but is also explains the start as a decision.

Brahma, supreme god and protector of the universe, arose from the ocean of existence [Anon (Upan)]
|
|
Full Idea:
Out of the infinite ocean of existence arose Brahma, first-born and foremost among the gods. From him sprang the universe, and he became its protector.
|
|
From:
Anon (Upan) (The Upanishads [c.950 BCE], 'Mundaka')
|
|
A reaction:
Brahma does not have eternal (or necessary) existence. Could Brahma cease to exist? I suppose we cannot ask what caused the appearance of Brahma? Is it part of a plan, or just luck, or some sort of necessity?

Earth, food, fire, sun are all forms of Brahman [Anon (Upan)]
|
|
Full Idea:
Earth, food, fire, sun - all these that you worship - are forms of Brahman.
|
|
From:
Anon (Upan) (The Upanishads [c.950 BCE], 'Chandogya')
|
|
A reaction:
In 'Taittiriya' food is named as the "chief of all things". Pantheism seems to arise from a desire that one's god should have every conceivable good, so in addition to power and knowledge, your god must keep you warm and healthy.

The gods are not worshipped for their own sake, but for the sake of the Self [Anon (Upan)]
|
|
Full Idea:
It is not for the sake of the gods, my beloved, that the gods are worshipped, but for the sake of the Self (Atman).
|
|
From:
Anon (Upan) (The Upanishads [c.950 BCE], 'Brihadaranyaka')
|
|
A reaction:
There is an uneasy selfish streak in all religions, which conflicts with their exhorations to altruism, and to the love of the gods. It also occurs in the exhortation of Socrates to be virtuous. 'Pure' altruism seems only to arise in the 18th century.

A man with desires is continually reborn, until his desires are stilled [Anon (Upan)]
|
|
Full Idea:
A man acts according to desires; after death he reaps the harvest of his deeds, and returns again to the world of action. Thus he who has desires continues subject to rebirth, but he in who desire is stilled suffers no rebirth.
|
|
From:
Anon (Upan) (The Upanishads [c.950 BCE], 'Brihadaranyaka')
|
|
A reaction:
I greatly prefer the Stoic idea (Idea 3066) that we should live according to nature, to this perverse longing to completely destroy our own nature and become something we are not. Play the cards you are dealt, which include desires.

The immortal Self and the sad individual self are like two golden birds perched on one tree [Anon (Upan)]
|
|
Full Idea:
Like two birds of golden plumage, the individual self and the immortal Self perch on the branches of the same tree. The individual self, deluded by forgetfulness of his identity with the divine self, bewildered by his ego, grieves and is sad.
|
|
From:
Anon (Upan) (The Upanishads [c.950 BCE], 'Mundaka')
|
|
A reaction:
Hinduism gives a much clearer and bolder picture of the soul than Christianity does. I don't see much consolation in the immortality of the wonderful Self, if my individual self is doomed to misery and extinction. Which one is me?
