17807 | To study formal systems, look at the whole thing, and not just how it is constructed in steps [Curry] |
Full Idea: In the study of formal systems we do not confine ourselves to the derivation of elementary propositions step by step. Rather we take the system, defined by its primitive frame, as datum, and then study it by any means at our command. | |
From: Haskell B. Curry (Remarks on the definition and nature of mathematics [1954], 'The formalist') | |
A reaction: This is what may potentially lead to an essentialist view of such things. Focusing on bricks gives formalism, focusing on buildings gives essentialism. |
17806 | It is untenable that mathematics is general physical truths, because it needs infinity [Curry] |
Full Idea: According to realism, mathematical propositions express the most general properties of our physical environment. This is the primitive view of mathematics, yet on account of the essential role played by infinity in mathematics, it is untenable today. | |
From: Haskell B. Curry (Remarks on the definition and nature of mathematics [1954], 'The problem') | |
A reaction: I resist this view, because Curry's view seems to imply a mad metaphysics. Hilbert resisted the role of the infinite in essential mathematics. If the physical world includes its possibilities, that might do the job. Hellman on structuralism? |
17808 | Saying mathematics is logic is merely replacing one undefined term by another [Curry] |
Full Idea: To say that mathematics is logic is merely to replace one undefined term by another. | |
From: Haskell B. Curry (Remarks on the definition and nature of mathematics [1954], 'Mathematics') |
9295 | Not only substances have attributes; events, actions, states and qualities can have them [Teichmann] |
Full Idea: It is not true that only substances have attributes; events, actions, states and qualities can all be characterized. | |
From: Jenny Teichmann (The Mind and the Soul [1974], Ch.2) | |
A reaction: This is why it is so important to distinguish the actual properties in nature from those that can be fancifully hypothesized by a linguistic being. Is there any limit to the possible number of levels of meta-properties? |
9293 | Body-spirit interaction ought to result in losses and increases of energy in the material world [Teichmann] |
Full Idea: Since the interaction of bodies themselves involves energy-flow, it looks as if interaction between body and spirit ought to result in losses and increases of energy in the material world. | |
From: Jenny Teichmann (The Mind and the Soul [1974], Ch.2) | |
A reaction: A nice statement of an important argument. It forces the dualist to go the whole way, asserting that not only is the mind immaterial, but that it can be active without energy, and cover its traces in the physical world. Doesn't look good. |
23053 | The great interest of the human race is cordial unity and unlimited mutual aid [Owen] |
Full Idea: It is the one great and universal interest of the human race to be cordially united, and to aid each other to the full extent of their capacities. | |
From: Robert Owen (works [1830]), quoted by John H. Muirhead - The Service of the State IV | |
A reaction: [Inscribed on his tomb in Newport, Shropshire] In the middle of the early industrial revolution, Owen worked hard for the rights of the people who worked in his factory. |
9292 | The Soul has no particular capacity (in the way thinking belongs to the mind) [Teichmann] |
Full Idea: On the whole, the Soul has no capacities which belong to it pre-eminently in the way that thinking 'belongs' to the mind. | |
From: Jenny Teichmann (The Mind and the Soul [1974], Ch.1) | |
A reaction: There are no phenomena which have to be saved by postulating a soul. It lacks a function within a human being, but it has a crucial function within a large theological picture. |
9294 | No individuating marks distinguish between Souls [Teichmann] |
Full Idea: There are no individuating marks which could serve to differentiate one Soul from another. | |
From: Jenny Teichmann (The Mind and the Soul [1974], Ch.2) | |
A reaction: Presumably they could have at least much identity as two different electrons (if they are in space-time?). It is hard to see why anyone would be interested in their 'own' immortality, if loss of all individuality was a condition. |
