21971 | Transcendental philosophy is the subject becoming the originator of unified reality [Kant] |
Full Idea: Transcendental philosophy is the act of consciousness whereby the subject becomes the originator of itself and, thereby, of the whole object of technical-practical and moral-practical reason in one system - ordering all things in God | |
From: Immanuel Kant (Posthumous notes [1799], 21:78, p.245), quoted by A.W. Moore - The Evolution of Modern Metaphysics 06 App | |
A reaction: This is evidently Kant's last word on the matter (c.1799), and Moore says he was drifting close to Fichte's idealism, in which reality is actually (sort of) created by our own minds. Disappointing! God's role here is unclear. |
6871 | We can't only believe things if we are currently conscious of their justification - there are too many [Goldman] |
Full Idea: Strong internalism says only current conscious states can justify beliefs, but this has the problem of Stored Beliefs, that most of our beliefs are stored in memory, and one's conscious state includes nothing that justifies them. | |
From: Alvin I. Goldman (Internalism Exposed [1999], §2) | |
A reaction: This point seems obviously correct, but one could still have a 'fairly strong' version, which required that you could always call into consciousness the justificiation for any belief that you happened to remember. |
6872 | Internalism must cover Forgotten Evidence, which is no longer retrievable from memory [Goldman] |
Full Idea: Even weak internalism has the problem of Forgotten Evidence; the agent once had adequate evidence that she subsequently forgot; at the time of epistemic appraisal, she no longer has adequate evidence that is retrievable from memory. | |
From: Alvin I. Goldman (Internalism Exposed [1999], §3) | |
A reaction: This is certainly a basic problem for any account of justification. It will rule out any strict requirement that there be actual mental states available to support a belief. Internalism may be pushed to include non-conscious parts of the mind. |
6874 | Internal justification needs both mental stability and time to compute coherence [Goldman] |
Full Idea: The problem for internalists of Doxastic Decision Interval says internal justification must avoid mental change to preserve the justification status, but must also allow enough time to compute the formal relations between beliefs. | |
From: Alvin I. Goldman (Internalism Exposed [1999], §4) | |
A reaction: The word 'compute' implies a rather odd model of assessing coherence, which seems instantaneous for most of us where everyday beliefs are concerned. In real mental life this does not strike me as a problem. |
6873 | Coherent justification seems to require retrieving all our beliefs simultaneously [Goldman] |
Full Idea: The problem of Concurrent Retrieval is a problem for internalism, notably coherentism, because an agent could ascertain coherence of her entire corpus only by concurrently retrieving all of her stored beliefs. | |
From: Alvin I. Goldman (Internalism Exposed [1999], §3) | |
A reaction: Sounds neat, but not very convincing. Goldman is relying on scepticism about short-term memory, but all belief and knowledge will collapse if we go down that road. We couldn't do simple arithmetic if Goldman's point were right. |
6875 | Reliability involves truth, and truth is external [Goldman] |
Full Idea: Reliability involves truth, and truth (on the usual assumption) is external. | |
From: Alvin I. Goldman (Internalism Exposed [1999], §6) | |
A reaction: As an argument for externalism this seems bogus. I am not sure that truth is either 'internal' or 'external'. How could the truth of 3+2=5 be external? Facts are mostly external, but I take truth to be a relation between internal and external. |
21236 | Instead of gravitational force, we now have a pervasive gravitational field [Farmelo] |
Full Idea: Physics replaced the notion that bodies exert gravitational force on each other by the more effective picture that the bodies in the universe give rise to a pervasive gravitational field which exerts a force on each particle. | |
From: Graham Farmelo (The Strangest Man [2009], 08) | |
A reaction: This still uses the word 'force'. I sometimes get the impression that gravity is the curvature of space, but gravity needs more. Which direction along the curvature are particles attracted? The bottom line is the power of the bodies. |
21235 | The Schrödinger waves are just the maths of transforming energy values to positions [Farmelo] |
Full Idea: Dirac showed that the Schrödinger waves were simply the mathematical quantities involved in transforming the description of a quantum based on its energy values to one based on possible values of its position. | |
From: Graham Farmelo (The Strangest Man [2009], 08) | |
A reaction: Does this eliminate actual physical 'waves' from the theory? |
21234 | Experiments show that fundamental particles of one type are identical [Farmelo] |
Full Idea: It is an established experimental fact ...that every single fundamental particle in the universe is the same and identical to all other particles of the same type. | |
From: Graham Farmelo (The Strangest Man [2009], 07) | |
A reaction: A loud groan is heard from the tomb of Leibniz. I'm unclear how experiments can establish this. If electrons have internal structure (which is not ruled out) then uniformity is highly unlikely. |
