An A Priori Order In his Private Notebooks 1914-1916 Wittgenstein writes: “The great question around which everything I write revolves is: Is there an a priori order in the world, and if so, of what does it consist?” The question is a good one (and highly metaphysical). In the Tractatus we read what looks like […]
Logical Phenomenology What would a phenomenological study of logic look like? It would investigate the modes of consciousness proper to the various categories of logic: variables, quantifiers, individual constants, connectives, predicates, premise and conclusion, rules of inference. This could be directed to a formal language such as we find in a logic textbook or it […]
Linguistic Phenomenology J.L. Austin described his method as “linguistic phenomenology”. It is highly likely that this is an allusion to Husserl’s phenomenology: Husserl’s work was well known in Oxford in Austin’s time and Gilbert Ryle had a special interest in Husserl (he was a colleague of Austin’s). A cheeky allusion, perhaps, but an allusion nonetheless. […]
Cancellation and Quotation Today I happened by chance on an article in Scientific American on panpsychism by Dan Falk. The second paragraph contains the sentences: “As philosopher David Chalmers asked: ‘How does the water of the brain turn into the wine of consciousness?’ He famously dubbed this quandary the ‘hard problem’ of consciousness.” In the […]
Data in Philosophy Every academic subject requires a source of data. Without data a subject cannot thrive, survive, or even exist. History requires written documents of the past. Archeology requires preserved artifacts. Microbiology requires data from microscopes. Anatomy requires dissections. Atomic physics requires data from supercolliders. Astronomy requires light readings from telescopes. Zoology requires observations […]
Determinacy of Translation The following seems logically possible: a speaker’s use of the word “rabbit” is accompanied by rapid changes in its meaning and denotation—at one moment meaning rabbit and at another meaning undetached rabbit part. This will not be apparent to an observer, since assent behavior will remain constant in the presence of rabbits […]
Does Truth Matter? Theories of truth are very various, as if people can’t decide what kind of thing truth is. Is it just another name for consistency (coherence), an inter-propositional relation? Is it nothing at all, mere repetition of the proposition said to be true? Is it some sort of abstract correspondence between proposition and […]
Against World-Making There is a view out there, made respectable by Nelson Goodman, that the world is made not found—or rather, worlds, plural.[1] Worlds are versions, verbiage, visions (to parody Goodman’s alliterative style). They are not discovered, or uncovered; they are constructed, built. Is there any truth to this trope (merit to this meme)? Note that […]
Geometrical Knowledge How do we come to have geometrical knowledge? How do we acquire geometrical concepts? The question has been around since Plato and his theory is still probably the best—we have such knowledge innately. But this doesn’t answer the question of what triggers the innate knowledge (it isn’t there fully formed from the start): […]
Quantified Logics Standard propositional logic contains no quantifiers. It simply replaces sentences with propositional variables (“schematic letters”) that remain unbound. But there is nothing to prevent us from introducing quantifiers that bind these variables, ranging over propositions. These can be objectual or substitutional, according to taste. They will be read “for all p” and “for […]
