Rather than taking the ontological fundamentality of an ideal microphysics as a starting point, this article sketches an approach to the problem of levels that swaps assumptions about ontology for assumptions about inquiry. These assumptions can be implemented formally via computational modeling techniques that will be described below. It is argued that these models offer…

The basic presupposition of cognitive science is that mental life is more complicated (or complex) than it appears; there is more to memory, attention, perception and the like, than meets the inner eye.  In most mainstream cognitive science, the hidden workings of the mind are treated as information processing systems…Read more here: The Complexity of Information…

Invariance is one of the most important notions in applications of mathematics. It is one of the key concepts in modern physics, is a computational tool that helps in solving complex equations, etc. In view of its importance, it is desirable to come up with a definition of invariance which is as general as possible.…
