Isn't every theory or model wrong?

All models are wrong, and many of them are useful. Newton's model of gravity is wrong in the close vicinity of a black hole, but perfectly useful to predict the paths of rocket launches from earth. ...

Isn't every theory or model wrong?

Before we can say that a model is wrong, we must first ask what exactly we would mean by that. In The Relativity of Wrong, Isaac Asimov discusses the degrees of wrongness of various models of the ...

Isn't every theory or model wrong?

A model is never "wrong", because a model is an abstraction of the territory, not the territory itself. By expecting a "right" model, you expect an absolutely identical territory, ...

Is the notion of "Complex System" a philosophy of science? Is it the opposite of Reductionism? Is it related to Holism?

A system is a complex system if its characteristic properties cannot be investigated by studying its components in isolation. A typical example of a complex system is the weather: One cannot study the ...

Is the notion of "Complex System" a philosophy of science? Is it the opposite of Reductionism? Is it related to Holism?

Short Answer Complex systems is a mathematical approach to studying certain objects of science, and is neither a science, nor a philosophy, but an approach that might be considered a combination of ...

Isn't every theory or model wrong?

In the philosophy of science, theories and models are recognized as being useful but limited. One famous philosophical slogan to epitomize that is "A map is not the territory.": The map–...

Isn't every theory or model wrong?

Physics attempts to explain how the real world works using models. These don’t attempt or claim to show the actual underlying mechanism of how things work, but they provide something that’s (a) ...

Is the notion of "Complex System" a philosophy of science? Is it the opposite of Reductionism? Is it related to Holism?

I would suggest that a complex system is simply a system which is not a simple system; where a simple system is one where you can see with a (possibly long) glance at the components every way it's ...

Is a model of inference needed for reasoning?

I'd be tempted to say that logic is not a model that we use to reason. It's a model, a representation, of how we reason (or should reason). People don't need to learn the rules of classical logic to ...

I don't remember which one, but I think it was Special Relativity that Einstein formulated purely on the basis of thought and did not keep anything to fit observed reality. This is false. There were ...

None of the physics models are wrong. You simply shouldn't take a model as saying "Reality is this". Statements like this are completely hopeless, because it is impossible to define reality. ...

Can we really measure something that's subjective?

The concept of 'measurement' depends on a collective agreement on a 'metric'. In other words (to use Wittgenstein's example), to say that something is one meter long we must all agree that some given ...

In logic, which came first: the semantic approach or the syntactic approach?

This is something of a chicken and egg problem. In a sense, the circularity is inherent in the very nature of logic. How are we to justify the rules of good reasoning if not by appealing to their ...

Is the notion of "Complex System" a philosophy of science? Is it the opposite of Reductionism? Is it related to Holism?

This is a personal opinion. I do research related to the Systems Theory for long years, and it's clear for me that the alleged discipline of complex systems is just an academic fraud. Classifying a ...

Your "essential reality" sounds a lot like observations of the world given the presupposition of phenomenology as emanating from direct realism. It presumes that somehow, we are in direct ...

Formally, an algorithm is "a specific set of instructions for carrying out a procedure". Bread is not an algorithm, but a set of instructions on how to bake bread is an algorithm. A formula ...

What is the value of a formal model in science?

First a point that may or may not be clear: we care about the 'target system'; the model is in many ways incidental. The target system is some system or process that exists in the real world, outside (...

What is the value of a formal model in science?

Suppose that M is a formal (mathematical) model and T is a target system. Then interpretation can be thought of as a map I:M->T. You can think of M and I as of "a picture" of T. The picture (as usual) ...
