Why your assumption that time should be quantised?

Time is a muddle of at least 3 different concepts.Historical time.The past, present,future concepts.Objective time, motion of the matter of the universe along a 4th dimension.Subjective time t, divisible into te and ti measured with clocks or internally within the 3 observable dimensions of space.

(There is also mathematical time that exists only as a term within mathematical formulae.)

Subjective time te gives a regular...


I agree that more than one definition of time is essential. I would suggest a minimum of 3. Although 1 of my 3 namely subjective time could be sub divided into two.ti, which is internally generated subjective time, relying mental reckoning based on internal circadian rhythms and input of general external environmental clues, and te which is time measured with an external timing device of any kind.

Already Lagrange wrote in 1757 in Theory des fonctions analytiques:

".. the principles of the differential calculus free from all considerations of the infinitely small or vanishing

quantities, or limits [etc.] reduced to the algebraic analysis of finite quantities."

Virtually all Wilhelminian mathematicians including Dedekind, G. Cantor, and Hilbert preferred to make this pragmatism a seemingly rigorous theory.

Therefore, the attempt by for instance Charles...
