Dear Maxim
"generalization of physical theories is associated not only with the acquisition of new concepts, but also with the abandonment of the old ones. Here it is necessary to note the following psychological factor: refusal of old, habitual physical concepts is given incomparably more difficult than the assimilation of new concepts not associated with such a refusal."
"Any major progress in physical science is connected not only with the creation of new concepts, but also with a critical revision of the old. And if this proves that some of the old concepts are not applicable to newly discovered phenomena, then one should part with them without regret"
"These more than 80 years old ideas do not lose their importance in our current approach to the foundations of cosmology and particle physics in their fundamental relationship".
I agree these points to be some of most important ideas needed to New physics approaches, in addition with terminological review ( since metaphors and overlaps may took place in habitual physical concepts.
Regarding to history of scientific development It has been something normal that scientists at time conclude their work and generalize to equation, based what they so far but second generations must be aware it's validity and if there is new discovery immediately must be profoundly interpreted while taking into account it Philsophical aspect, other wise misinterpretation may lead chain of misconceptions.
A best example is tremendous situation of the separation (due to matter of misinterpretation) between Classical Physics and the Quantum Mechanics.
Linking them to the Fundamental nature of Gravity, there is 232 years old PUZZLE namely Coulomb's Law which have not valid reason last 85 years (since 1932 last nucleon discovery), but I m not quite sure if today's Scientists are aware to it and it's consequences. I think the appropriate and inspiring question is;
Considering to Coulomb's law a statement that says "same type of charge repell and different type of charge attracts".
How Coulomb would conclude his law, if he know that nuclei has protons that same type of charge are attracting each other and with the neutrons? and they can be divided into fractions of charge?.
One may answer freely and open mindedly to the question, but I believe it rests upon all the solution needed, such as; Unification GR and QM and also Forces Unification (GUT).
On the other hand terminological review, redefinition, rethinking...... with ontological/Philosophical aspect would be necessary since modern physics is unbounded from Natural Philosophy.
Here is may essay; FUNDAMENTAL SINGULARITY OF ALL PHYSICAL SCIENCE
