Dear Jean-François,
Your ideas are close to me in spirit deep Cartesian doubt.
Weierstrass expressed the soap so important for mathematicians and physicists: "The final object always to be kept in mind is to arrive at a correct understanding of the foundations of the science."
Mathematics and physics lost existential certainty in the 19th century. the problem of "bases" and "beginning" of fundamental knowledge is unsolved. Fundamental knowledge, mathematics and physics, requires a deep ontological justification (basification). It is necessary to introduce an ontological standard justification (basification) in fundamental physics along with the empirical standard . Mathematics should also make a sharp ontological turn.
Axiom? -Yes. The principle? - Yes. But it must be the deepest ontological axiom and principle: super axiom and super principle. It must come from the deepest understanding of "matter", "measure", "logos", "eidos" in the spirit of Plato's ontology and dialectics. I believe that only the deepest ontological turn of the fundamental science will provide an opportunity to get out of the "crisis of understanding", "crisis of interpretation and representation" to the new heuristics.
I invite you to see my analysis of the philosophical foundations of mathematics and physics, the method of ontological constructing of the primordial generating structure, "La Structure mère" as the ontological framework, carcass and foundation of knowledge, the core of which - the ontological (structural, cosmic) memory. I believe that the scientific picture of the world should be the same rich senses of the "LifeWorld» (E.Husserl), as a picture of the world lyricists , poets and philosophers.
Par ailleurs, Vladimir Voevodsky, auteur univalentes fondements des mathématiques, dans une interview exprimé un point intéressant et important: "Ce que nous appelons aujourd'hui la crise de la science russe ne est pas seulement une crise de la science russe. Ce est une crise de la science mondiale. Des progrès réels sera un combat très sérieux entre science et religion qui mettra fin à leur association. Et je ne ai pas besoin pour battre le le visage."
Sincèrement,
Vladimir
