Ponderings of science, philosophy, history, society, and many other topics
Scientific realism vs instrumentalism A long standing debate in the philosophy of science is about what our best scientific theories tell us. Some argue that they reveal true reality, that is, they are real. Others that scientific theories are only useful prediction frameworks, instruments useful in the creation of technology, but that taking any further … Continue reading Why I’m an ontic structural realist
Scientific breakthroughs often begin with someone saying, "Don't panic. This crazy sounding assumption is just to make the math work." Nicholaus Copernicus, when he developed his theory of heliocentrism (the earth orbits the sun), was operating from a scientific realist view. In other words, he thought his system reflected actual reality, or at least reflected it … Continue reading Is it just the math?
In one of the final chapters of his book: Reality+: Virtual Worlds and the Problems of Philosophy, David Chalmers asks, have we fallen from the Garden of Eden? "Eden" in this case is a metaphor for living in a world where everything is as it seems, matching our pre-theoretical view of reality. In Eden, everything exists … Continue reading Universal functionalism

He identifies different types of information: semantic, structural, and symbolic. Semantic information is what we colloquially think of as information, it's the patterns that tell someone or something about reality. A map of a city … Continue reading Information, computation, and reality
The other day I did a post on structural realism. If you found that interesting, you might find this interview of James Ladyman by Sean Carroll worth listening to (or reading, since there's a transcript). Ladyman is the author of the SEP article on structural realism I linked to, and seems to be a major … Continue reading Interviews of James Ladyman on metaphysics
In the scientific realism vs instrumentalism debate, realism is the position that the elements of a scientific theory represent reality. So when general relativity talks about space warping, space really is warping. Instrumentalism, or anti-realism, is the stance that scientific theories are just prediction mechanisms, with no guarantee that they represent reality. Under instrumentalism, general … Continue reading Structural realism, a way to be a scientific realist?
