RationalWiki Upgrade 2017

Since this morning, RationalWiki.org is running on MediaWiki 1.27.

This is a bit of a facade, since it's just a snapshot which Tim Starling imported and upgraded as a dry run.

This database will be dropped and recreated, so any edits you make will be lost. Sorry!

In addition, search and several other functions are not done yet and will give PHP errors.

Philosophy of science

Icon philosophy of science.svg

Philosophical naturalism is the doctrine that the natural world is all there is — in other words, that the supernatural is definitionally impossible, since whatever is shown to exist (via affecting the natural world) is clearly part of that same natural world.[1]

Basically all scientists (and a vast majority of modern philosophers) adhere to some version of naturalism, which is why reference to supernatural or miraculous effects or forces is frowned upon in academia.[2]


[edit] Metaphysical or methodological?

Two refinements of the term "naturalism" that are of use for any rationalist to know are methodological naturalism (on the one hand) and metaphysical naturalism (on the other).

Science is itself a process based on methodological naturalism, i.e. treating the world as if metaphysical naturalism was the case, but without actually taking a stand on matters philosophical (outside of method).[3]

Metaphysical naturalism, on the other hand, is what it means to extend scientific principles all the way into the farthest reaches of philosophy. Scouting future territory for the natural sciences to conduct research in (and defending naturalism generally), philosophical naturalism is what Richard Carrier simply describes as "science with less data",[4] operating in anticipation of scientific data where possible. This approach signifies the single least woo-prone way in which to engage any given speculatory topic, aside from the cop-out philosophically agnostic view of methodological naturalism.

Metaphysical naturalism is more or less a basic precept of all modern analytic philosophyWikipedia's W.svg, which was itself formed partially in protest of the centuries of woo that had accreted in philosophy (notably German idealism) prior to the explosive triumph of modern science in the last 150 years or so.

Strict adherence to methodological naturalism creates a theoretical space in which positions like NOMA may be compatibly held by those who chose to do so. Methodological naturalism is, as such, the "minimum position" to which science is reducible[5] — and it still entails not giving the time of day to woo-meistry.

In that context, metaphysical naturalism simply means "closing" said NOMA/gaps space by taking the fight all the way against theology and accommodationism.[6]

[edit] Origins in methodological naturalism

Philosophical naturalism is arguably the logical result of methodological naturalism. Methodological naturalism accepts that there is no way to contact, detect, or otherwise empirically observe the supernatural. In consequence methodological naturalists believe the scientific method to be the best way to determine the truth about reality. Because supernatural, intelligent forces, if they exist, are unpredictable and hence unrepeatable naturalists reject the possibility of supernatural or magical intervention in the physical world.

Philosophical naturalists take these beliefs one step further and reject the existence of the supernatural altogether, citing the utter lack of empirical evidence. Because of the absence of scientific evidence backing up religion, most philosophical naturalists are also atheists (or at most deists).

[edit] Opposition by religion

Arrayed against philosophical naturalism are religious schools of thought which argue for the existence of the supernatural alongside the natural. In order to compete with science they have created pseudoscientific theories such as intelligent design which supposedly prove supernatural intervention in natural phenomena. However, they also assert that the supernatural is somehow immune to science. These theories, therefore, work about as well as cargo cults.

[edit] Do not equate with

Although these are related to naturalism, there are differences:

[edit] Materialism

All things are composed of matter and that all emergent phenomena (such as thoughts) are the result of material interactions.

[edit] Physicalism

The only things are those subject to the laws of physics.

[edit] Scientism

All that can be known is what science tells us.

[edit] Nominalism

Abstract objects exist as predicates, not universals (as opposed to Platonism).

  1. It's a beautifully consistent position, unlike other antiquated anti-empirical views, e.g. variants of idealism.
  2. Really — naturalism is quite literally the reason why it's not okay to appeal to a friendly ghost named Casper in science papers.
  3. This helps explain why skeptics are the ones to take on the cranks; actual scientists are generally busy doing science, and could care less about the relentless flora of stillborn anti-scientific propositions out there. To the naturalists, nature — not man — is the arbiter, and we walked on the moon as a result.

  6. I.e., it's only metaphysical naturalism (out of the two) which finds it philosophically inconsistent for people to, say, perform perfectly rigorous science during the day, and then go home to privately worship invisible phantasms.
