“There is certainly something to the thought that certain classic papers of Putnam and Quine offer perhaps the closest thing to be found in twentieth-century philosophy to an attempt to rehabilitate Descartes's claim that it would be hubris for us to assert of an omnipotent God that He would be inexorably bound by the laws of logic - those laws which happen to bind our finite minds. In a move which is characteristic of much of contemporary naturalistic thought (both in and out of the academy), science is substituted for God. Cartesianism in the philosophy of logic, freed of its theological trappings, becomes the view that it would be hubris for us to assert of the ongoing activity of scientific inquiry that it will be forever bound by the laws of classical logic - those principles which happen to be most fundamental to our present conceptual scheme. The contrast is now no longer, as in Descartes, between the infinite powers of man and the infinite powers of God, but rather between the limits of present scientific thought and the infinite possibilities latent in the future of science as such ... If Descartes is led by a sense of theological piety to insist that God can do anything - no matter how inconceivably it may be to us - the contemporary ultra-empiricist is led by an equally fervent sense of naturalistic piety to insist that the science of the future might require a revision of any of our present axioms of thought - no matter how unacceptable such a revision might seem by our present lights. The exploration of the contours of possibility belongs to the business of the physicists. In this regard, we philosophers must issue them a blank check - it would compromise our standing as underlaborers to put a ceiling on how much they can spend. To paraphrase Descartes on God: we must not conclude that there is a positive limit to the power of science on the basis of the limits of our own (present) powers of conception. All of its hostility to theology notwithstanding, this contemporary form of piety is, in a sense, no less religious (in its unconditional deference to a higher authority) than Descartes's - it has simply exchanged one Godhead for another. But, unlike Descartes, precisely because it is overly hostile to theology, it is able easily to blind itself to the fact that it is a form of piety.” ScienceReligionLogicTheologyPietyLawsDescartes Book:The Logical Alien: Conant and His Critics Source: The Logical Alien: Conant and His Critics
“In Frege’s conception of logic, a logical law states an absolutely general truth—one whose truth every rational being must, on pain of contradiction, acknowledge. In later Wittgenstein’s practice, a grammatical remark inherits an aspect of Frege’s conception of the logical. On a proper understanding of a grammatical remark, it articulates a truism— something that admits of no contrary—hence something that every speaker of the language must acknowledge. Or conversely, if there is something in a given candidate grammatical remark that proves to admit of disagreement, then the remark in question cannot serve its methodological role. It fails to bring into view a point of (what later Wittgenstein calls) grammar. Grammatical remarks acquire their point—that is, our need for such reminders derives—from our attempting but failing to achieve a proper reflective understanding of our way around our own language. If the grammatical remark serves its purpose, what is thereby acknowledged is something that can come into view only against the background of a prior failed attempt to achieve a perspicuous overview of our own concepts. A Wittgensteinian grammatical remark comes to life as such only against the background of a philosophical confusion. Logic or grammar for later Wittgenstein, pace Frege, could qualify as a science only if philosophy is one. This also means that, for later Wittgenstein, unlike for Frege, there is no preexisting stock of propositions that constitutes all of the logico-grammatical truths there are. In potentiality there are perhaps indefinitely many, but in actuality the only remarks that actually exercise the power to disclose a philosophico-grammatical truth, for later Wittgenstein, are those that allow us to make progress with the problems that actually vex us in philosophy.” PhilosophyTruthScienceLanguageProgressGrammarFrege Book:The Logical Alien: Conant and His Critics Source: The Logical Alien: Conant and His Critics
