Philosophical discourse may be logically, linguistically, psychologically, sociologically and ideologically analyzed. One can question whether philosophical discourse has any claim to veracity or value. One can be amazed by the hubris and confidence of philosophers and question the epistemic or intrinsic public value of the discourse they produce. One can inquire whether philosophers fail to question the assumptions they tacitly assume, or whether some positions be never stately clearly but only insinuated (cf. Ernst Gellner's Words and Things). One can question whether self-proclaimed "rigorous" philosophy is actually as "rigorous" as it claims to be and question whether such a "rigor" be not entirely illusory and only based on stylistic mimicry and convoluted jargon masking the lack of any possibility of formalization in an axiomatic-deductive system. One can question whether philosophical discourse be not a mere language game (like the crossword) based on vagueness, ambiguity and unconscious association, tolerated due to the loftiness of the object of discourse, the stylistically "scientific" semblance of the discourse itself, specially when focused on technical topics in logic and language. Surely we must reject a game based on the dynamics and structure of human consciousness which yet denies outright the underlying role of human consciousness in the spirit of: pay no attention to the man behind the curtain! Philosophy can well seems scientific yet be not so and produce arguments that on the surface seem to be like a logical mathematical proof but fall utterly short of it. And, most importantly, be completely lacking criteria for veracity and value. And what are we to make of philosophers who downplay or trivialize introspective psychology, mathematical linguistics and mathematical linguistic analysis (the only way to go beyond circularity in linguistics) or the universal ethical principles of human and animal rights? All human activities with value have public, objective criteria. Philosophy does not have such criteria. Contrary to most academic critiques of academic philosophy the central flaw is not ignoring fundamental domains of human experience and the human condition (which is a valid enough point) but the claim to analytical and rigorous while being not so and lacking any objective public criteria of veracity or value. A mathematical proof can be formalized and checked in a proof assistant such as Agda. A theory in natural science can be confronted with experimental data and evidence. A work of art is received by the public.. But philosophy has no criteria beyond "deemed acceptable to be published in journal X by the editor and reviewers A,B,C,...". A tacit assumption and error is that the mathematical formalization of (a relevant fragment of) natural language is neither possible nor desirable for philosophy. Another one is (often tied to physicalist dogmatism): introspective psychology (as in Hume, William James and Brentano) is of little value and not a source of philosophical insight and progress. And if to this we add to this the rejection of the marvelous metaphoric, poetic and analogical capabilities of natural language, we come to the conclusion that such philosophy is mere verbiage, a linguistic production without veracity or value which merits careful linguistic, psychological and cultural diagnosis and analysis.
A note on the formalization of natural language. When two people sit down to play a game they have reached an agreement. The pieces on the board and the rules will represent the game but are not themselves the game. The agreement is that the board, pieces and rules will stand for the game. A formalization of a fragment of natural language will take the form of a formal system incorporating a series of formal definitions which a group of people will agree represents a certain fragment of natural language. This group will agree (based on a perceived contextual adequacy) to abide by the rules of the game of such a formal system for the purposes of certain arguments or debates - they agree that the formal system and its moves stand for the linguistic activity of the debate. The formalization of natural language is in a way a return to the original essence of natural language. Indeed as mentioned in the conclusion of our Analyticity, Computability and the A Priori, it is through the reliving and showing forth of the process of our psycho-cognitive development that we may hope to ultimately see the light regarding the problems of philosophy. Just as Kant distinguished between a legitimate and illegitimate use of reason (the transcendental illusion once the basic foothold of logic and introspective intuition are abandoned) so too we must distinguish between a perfectly legitimate use and application of language (in which the adequacy of language is unquestionable, independently of any formalization) and an illegitimate use and domain as exemplified by the naive linguistic productions of philosophy. The formalization of natural language is a necessary critique, a judgment, a challenge and a sifting.
