Once I asked Altshuller: "The limit of possible in technology is determined by
physics (and chemistry).
But what determines the limit of possible in physics ?"
- Meta-physics, - Altshuller replied, - philosophy.
- And what determines the limit of possible in meta-physics ? - I continued, - meta-meta-physics ? And in meta-meta-physics - meta-meta-meta-physics ?"
He was definitely right that the limit of possible in physics (and science on the whole) is determined by meta-physics (or meta-science in general) although meta-science is not reduced to philosophy only. In mathematics, for instance, meta-mathematics is by no means a philosophy.
Nevertheless, the idea born in that discussion that the entire body of the human knowledge can be covered by the set of series, discipline, meta-discipline, meta-meta-discipline, etc. , where each subsequent element determines the limit of possible in the previous one, is an important contribution to philosophy.
