Is the notion of "Complex System" a philosophy of science? Is it the opposite of Reductionism? Is it related to Holism?
I have tried to come to terms with the notion of "complex systems" of which I heard in one of the lessons at school though without too much depth. I grasp that a complex system is such that the behavior of the elements in the system do not yield…

What is the value of a formal model in science?
In science we often use formal models (by which I mean a mathematical structure composed of assumptions, variables, and equations, which might be solved/simulated to derive analytical insights and/or testable hypotheses). If the objective is to…

How do we use topology to model knowledge?
The topology of knowledge: In this application, topological spaces are used to model the structure of knowledge, where the open sets correspond to coherent bodies of knowledge and the closure operation represents the process of inference.

In logic, which came first: the semantic approach or the syntactic approach?
Logic is today developing in many, very different directions. But the basic distinction between the semantic approach (truth, "⊨") and the syntactic one (provability, "⊢") is still important and taught in all basic logic courses.

Question regarding the stipulated 'domain of discourse' for models of first-order sentences
Assume 'S' is a first-order sentence about a subject 'Z'.
When one stipulates a Model for 'S' with a domain 'D' does one always assume that the domain will contain all the objects within the subject 'Z'?
E.g. Let S = 'All lizards like flies'
Then…

Some definitions (from what I can tell):
A multigraph is a graph where a node can connect via multiple edges.
A hypergraph is a graph where a single edge can connect more than two nodes. Alternatively, there are nodeless edges available in this…

What is the difference between a model and algorithm?
I would say that an algorithm is a private case of model because it describes how something generally works --- just mathematically.

Philosophy of science: Determinism and indeterminism in statistical methods of science
A variable is modeled as a random variable in a statistical model, often without reference to the question of whether it is random in reality. For example, when the outcome of a coin flip is modeled as a random variable, no one asks the question…

Ten years ago, I read Vankatesh Rao's blog post The Gervais Principle. It blew my mind, as it did the minds of many other people. It quickly became Rao's most popular blog post entry, prompting a series of blog posts on the same subject and an…

Is this metalogical diagram a reasonable presentation of untyped logics?
Diagram 1 represents my attempt to present the main components of classical predicate logic in a simple diagrammatic form. Diagram 1 is about logic, not in a particular logic, hence the term metalogical.
This diagram is divided in into two sections,…

How do the philosophical notions of schemas and paradigms differ?
In analytical philosophy, both schemas and paradigms are powerful conceptual structures for modeling phenomena, and I wonder which features define and differentiate them.
