Naturalism
Naturalism is a unifying view of philosophy and science. It is an attitude about how philosophy should be done (a meta-philosophy) and about how philosophy relates to science. Regardless of how one views the realism debate (discussed in the previous outline), naturalism shows a provocative, unifying way of viewing the projects of philosophy and science.
Here we also discuss additional meta-philosophical issues, other worldviews in constrast to naturalism, and the culture wars between worldviews.
This could have been called the outline of “Meta-philosophy.”

What is naturalism?
First pass
- Natural philosophy
Sellars:
The aim of philosophy, abstractly formulated, is to understand how things in the broadest possible sense of the term hang together in the broadest possible sense of the term. Under ‘things in the broadest possible sense’ I include such radically different items as not only ‘cabbages and kings,’ but numbers and duties, possibilities and finger snaps, aesthetic experience and death. To achieve success in philosophy would be, to use a contemporary turn of phrase, to ‘know one’s way around’ with respect to all these things…1
TODO: Manifest image and scientific image - Sellars
- Sellars, W. (1963). “Philosophy and the scientific image of man” in Sellars (1963)
- Sellars used the term “synoptic vision” for the kind of coherent understanding of everything together.
Maddy defines naturalism:
These days, as more and more philosophers count themselves as naturalists, the term has come to mark little more than a vague science-friendliness. To qualify as unnaturalistic, a contemporary thinker has to insist, for example, that epistemology is an a priori discipline with nothing to learn from empirical psychology or that metaphysical intuitions show quantum mechanics to be false.2
So our inquirer will continue her investigation of the world in her familiar ways, despite her encounter with Descartes and his meditator. She will ask traditionally philosophical questions about what there is and how we know it, just as they do, but she will take perception as a mostly reliable guide to the existence of medium-sized physical objects, she will consult her astronomical observations and theories to weigh the existence of black holes, and she will treat questions of knowledge as involving the relations between the world—as she understands it in her physics, chemistry, optics, geology, and so on—and human beings—as she understands them in her physiology, cognitive science, neuroscience, linguistics, and so on. While Descartes’s meditator begins by rejecting science and common sense in the hope of founding them more firmly by philosophical means, our inquirer proceeds scientifically and attempts to answer even philosophical questions by appeal to its resources. For Descartes’s meditator, philosophy comes first; for our inquirer, it comes second—hence ‘Second Philosophy’ as opposed to ‘First.’ Our Character now has a name: she is the Second Philosopher.3
Jacobs:
Naturalism is an approach to philosophical problems that interprets them as tractable through the methods of the empirical sciences or at least, without a distinctively a priori project of theorizing.4
Naturalism could be defined as a support for philosophy that is filtered for plausibility given the information from science.5 See the Outline on the science method.
Maudlin gives clear naturalist attitude at the start of The Metaphysics within Physics:
[M]etaphysics, insofar as it is concerned with the natural world, can do no better than to reflect on physics. Physical theories provide us with the best handle we have on what there is, and the philosopher’s proper task is the interpretation and elucidation of those theories. In particular, when choosing the fundamental posits of one’s ontology, one must look to scientific practice rather than to philosophical prejudice.6
Papineau:
The term “naturalism” has no very precise meaning in contemporary philosophy. Its current usage derives from debates in America in the first half of the last century. The self-proclaimed “naturalists” from that period included John Dewey, Ernest Nagel, Sidney Hook and Roy Wood Sellars. These philosophers aimed to ally philosophy more closely with science. They urged that reality is exhausted by nature, containing nothing “supernatural,” and that the scientific method should be used to investigate all areas of reality, including the “human spirit” (Krikorian 1944, Kim 2003).
So understood, “naturalism” is not a particularly informative term as applied to contemporary philosophers. The great majority of contemporary philosophers would happily accept naturalism as just characterized—that is, they would both reject “supernatural” entities, and allow that science is a possible route (if not necessarily the only one) to important truths about the “human spirit.”7
Second pass
A very diverse set of thinkers are often characterized as naturalists or aligned with naturalism, at the expense of much clarity in the term, but naturalism generally consists of varying degrees of either or both:
- epistemological/methodological naturalism - an epistemic respect for science and empiricism; a methodological commitment to the scientific method of justifying empirical claims as a route to knowledge, if not the chief or perhaps (with a sufficiently broad definition) the only route to knowledge. Science should be guiding in what we claim to know.
- metaphysical/ontological naturalism - has a variety of claims and interpretations, but they center on the premise that if we have any claim to what there is, it better be informed by and consistent with science. It often involves a skepticism of a priori metaphysics (statements about what there is that come prior to empirical information), and sometimes has further qualified ontological commitments to the products of science, which concerns the debate of scientific realism. Another claim associated with ontological naturalism and closely related to epistemological naturalism is a rejection of ontologies to which we do not have demonstrable, access i.e. supernatural entities, which can be seen as a claim to a type of monism as opposed to dualism about ontology. There is one (natural) world. At the least, it is a claim that science should be guiding in what we claim there is.

Riepe on the characteristics of naturalism in Indian thought:
- The naturalist accepts sense experience as the most important avenue of knowledge.
- The naturalist believes that knowledge is not esoteric, innate, or intuitive (mystical).
- The naturalist believes that the external world, of which man is an integral part, is objective and hence not “his idea” but an existent apart from his, your, or anyone’s consciousness.
- The naturalist believes that the world minifests order and regularity and that, contrary to some opinion, this does not exclude human responsibility. This order cannot be changed merely by thought, magic, sacrifice, or prayer, but requires an actual manipulation of the external world in some physical way.
- The naturalist rejects supernatural teleology. The direction of the world is caused by the world itself.
- The naturalist is humanistic. Man is not simply a mirror of deity or the absolute but a biological existent whose goal it is to do what is proper to man. What is proper to man is discovered in a naturalistic context by the moral philosopher.11

When issues have sharp and rich answers they get specialized into a science, and philosophy is the nursery of burgeoning sciences.
— Ryan Reece (@RyanDavidReece) February 18, 2022
Descartes (often seen as anti-naturalist, explain, but he) wrote in 1644,
Philosophy as a whole is like a tree; of which the roots are Metaphysics, the trunk is Physics, and the branches emerging from this trunk are all the other branches of knowledge. These branches can be reduced to three principal ones, namely, Medicine, Mechanics, and Ethics.16
Reichenbach:
What unites the members of this group is not the maintenance of a philosophical “system,” but a community of working methods—an agreement to treat philosophical problems as scientific problems whose answers are capable of soliciting universal assent. Philosophical problems, in other words, do not differ in principle from problems of the positive sciences. The strength of this group lies in its common working program and not in a common doctrine—a program which distinguishes it from philosophical sects, and makes possible progress in research.17
Russell:
In the welter of conflicting fanaticisms, one of the few unifying forces is scientific truthfulness, by which I mean the habit of basing our beliefs upon observations and inferences as impersonal, and as much divested of local and temperamental bias, as is possible for human beings. To have insisted upon the introduction of this virtue into philosophy, and to have invented a powerful method by which it can be rendered fruitful, are the chief merits of the philosophical school of which I am a member. The habit of careful veracity acquired in the practice of this philosophical method can be extended to the whole sphere of human activity, producing, wherever it exists, a lessening of fanaticism with an increasing capacity of sympathy and mutual understanding. In abandoning a part of its dogmatic pretensions, philosophy does not cease to suggest and inspire a way of life.18

Sellars:
Philosophy in an important sense has no special subject-matter which stands to it as other subject-matters stand to other special disciplines. If philosophers did have such a special subject-matter, they could turn it over to a new group of specialists as they have turned other special subject-matters to non-philosophers over the past 2500 years, first with mathematics, more recently psychology and sociology, and, currently, certain aspects of theoretical linguistics. What is characteristic of philosophy is not a special subject-matter, but the aim of knowing one’s way around with respect to the subject-matters of all the special disciplines.20

Viena Circle manifesto:
The scientific world conception is characterised not so much by theses of its own, but rather by its basic attitude, its points of view and direction of research. The goal ahead is unified science. The endeavour is to link and harmonise the achievements of individual investigators in their various fields of science. From this aim follows the emphasis on collective efforts, and also the emphasis on what can be grasped intersubjectively; from this springs the search for a neutral system of formulae, for a symbolism freed from the slag of historical languages; and also the search for a total system of concepts.22
Bunge:
I believe that a philosophy is spineless without ontology, confused without semantics, acephalous without epistemology, deaf without ethics, paralytic without social philosophy, and obsolete without scientific support—and no philosophy at all with neither.23

Carnap:
If we allot to the individual in philosophical work as in the special sciences only a partial task, then we can look with more confidence into the future: in slow careful construction insight after insight will be won. Each collaborator contributes only what he can endorse and justify before the whole body of his co-workers. Thus stone will be carefully added to stone and a safe building will be erected at which each following generation can continue to work.26
Bunge:
Good philosophy is worth doing because it is a vantage point for the study of anything, whether concrete things or abstract ideas. Indeed, although it may not see the world, good philosophy helps looking at it—just as bad philosophy blocks the view of ideas and things, in denying that there are any, or in claiming that they can be understood without the help of either reason or experience.
If good philosophy is both valuable and currently in short supply, then it should be reconstructed. Which materials and tools should be used to rebuild philosophy? I suggest that the materials—the substance—are provided by science and technology, as well as by the history of philosophy; and the tools—the form—by logic and mathematics. This is, at least, the kind of philosophy I care for: one capable of tackling interesting philosophical questions in the light of the best available factual knowledge, and with the help of precision tools forged by formal science.27

Kant in his Prolegomena to Any Future Metaphysics:
My object is to persuade all those who think Metaphysics worth studying, that it is absolutely necessary to pause a moment, and, neglecting all that has been done, to propose first the preliminary question, ‘Whether such a thing as metaphysics be at all possible?’
If it be a science, how comes it that it cannot, like other sciences, obtain universal and permanent recognition? If not, how can it maintain its pretensions, and keep the human mind in suspense with hopes, never ceasing, yet never fulfilled? Whether then we demonstrate our knowledge or our ignorance in this field, we must come once for all to a definite conclusion respecting the nature of this so-called science, which cannot possibly remain on its present footing. It seems almost ridiculous, while every other science is continually advancing, that in this, which pretends to be Wisdom incarnate, for whose oracle every one inquires, we should constantly move round the same spot, without gaining a single step. And so its followers having melted away, we do not find men confident of their ability to shine in other sciences venturing their reputation here, where everybody, however ignorant in other matters, may deliver a final verdict, as in this domain there is as yet no standard weight and measure to distinguish sound knowledge from shallow talk.29

Discussion
TODO: While promoting the careful gathering of empirical information, naturalism is not against (largely non-empirical) rational pursuits like mathematics. Indeed some naturalist may even see logic and mathematics as scientific pursuits of a priori truths.
TODO: Naturalism shares much in common with schools of thought surrounding positivism, through its respect for science and skepticism of a priori metaphysics, but naturalism is a more general distinction, being a more much longer thread throughout the history of philosophy and science.
Quine in “Natural kinds”:
At this point let me say that I shall not be impressed by protests that I am using inductive generalizations, Darwin’s and others, to justify induction, and thus reasoning in a circle. The reason I shall not be impressed by this is that my position is a naturalistic one; I see philosophy not as an a priori propaedeutic or groundwork for science, but as continuous with science. I see philosophy and science as in the same boat—a boat which, to revert to Neurath’s figure as I so often do, we can rebuild only at sea while staying afloat in it. There is no external vantage point, no first philosophy. All scientific findings, all scientific conjectures that are at present plausible, are therefore in my view as welcome for use in philosophy as elsewhere.41
More Quine:
I also expressed, at the beginning, my unswerving belief in external things—people, nerve endings, sticks, stones. This I reaffirm. I believe also, if less affirmly, in atoms and electrons, and in classes. Now how is all this robust realism to be reconciled with the barren scene that I have just been depicting? The answer is naturalism: the recognition that it is within science itself, and not some prior philosophy, that reality is properly to be identified and described.42
Opening lines to ETMG:
This is a polemical book. One of its main contentions is that contemporary analytic metaphysics, a professional activity engaged in by some extremely intelligent and morally serious people, fails to qualify as part of the enlightened pursuit of objective truth, and should be discontinued.43

Criticism
Aquinas:
Whether sacred doctrine is nobler than other sciences?
Objection 1: It seems that sacred doctrine is not nobler than other sciences; for the nobility of a science depends on the certitude it establishes. But other sciences, the principles of which cannot be doubted, seem to be more certain than sacred doctrine; for its principles—namely, articles of faith—can be doubted. Therefore other sciences seem to be nobler.
…
On the contrary, Other sciences are called the handmaidens of this one: “Wisdom sent her maids to invite to the tower” (Prov. 9:3).
I answer that, Since this science is partly speculative and partly practical, it transcends all others speculative and practical. Now one speculative science is said to be nobler than another, either by reason of its greater certitude, or by reason of the higher worth of its subject-matter. In both these respects this science surpasses other speculative sciences; in point of greater certitude, because other sciences derive their certitude from the natural light of human reason, which can err; whereas this derives its certitude from the light of divine knowledge, which cannot be misled: in point of the higher worth of its subject-matter because this science treats chiefly of those things which by their sublimity transcend human reason; while other sciences consider only those things which are within reason’s grasp. Of the practical sciences, that one is nobler which is ordained to a further purpose, as political science is nobler than military science; for the good of the army is directed to the good of the State. But the purpose of this science, in so far as it is practical, is eternal bliss; to which as to an ultimate end the purposes of every practical science are directed. Hence it is clear that from every standpoint, it is nobler than other sciences.
Reply to Objection 1: It may well happen that what is in itself the more certain may seem to us the less certain on account of the weakness of our intelligence, “which is dazzled by the clearest objects of nature; as the owl is dazzled by the light of the sun” (Metaph. ii, lect. i). Hence the fact that some happen to doubt about articles of faith is not due to the uncertain nature of the truths, but to the weakness of human intelligence; yet the slenderest knowledge that may be obtained of the highest things is more desirable than the most certain knowledge obtained of lesser things, as is said in de Animalibus xi.80

Mere experience is no more a substitute for thinking than reading is. Pure empiricism is related to thinking as eating is to digestion and assimilation.

Boghossian:
Especially within the academy, but also and inevitably to some extent outside of it, the idea that there are “many equally valid ways of knowing the world,” with science being just one of them, has taken very deep root. In vast stretches of the humanities and social sciences, this sort of “postmodernist relativism” about knowledge has achieved the status of orthodoxy. I shall call it (as neutrally as possible) the doctrine of
Equal Validity:
There are many radically different, yet “equally valid” ways of knowing the world, with science being just one of them.95
Scruton:
In our present circumstances the impression arises that, outside the hard sciences, just about anything goes, and that the humanities have neither a method nor a received body of knowledge, it being up to the professor to decide what to teach in his class.96
Art critics have a discipline, and it is one that involves reasoning and judgment. It is not a science, and what it describes forms no part of the physical world, which does not contain Olympia or anything else that you see in Manet’s painting. Yet someone who thought that art criticism is therefore deficient, and ought to be replaced by the study of pigments, is surely missing the point. There are forms of human understanding that can be neither reduced to science nor enhanced by it.97
Carnap on Wittgenstein:
there was a striking difference between Wittgenstein’s attitude toward philosophical problems and that of Schlick and myself. Our attitude toward philosophical problems was not very different from that which scientists have toward their problems.
…
His point of view and his attitude toward people and problems, even theoretical problems, were much more similar to those of a creative artist than to those of a scientist; one might almost say, similar to those of a religious prophet or a seer…. When finally, sometimes after a prolonged arduous effort, his answers came forth, his statement stood before us like a newly created piece of art or a divine revelation … the impression he made on us was as if insight came to him as through divine inspiration, so that we could not help feeling that any sober rational comment or analysis of it would be a profanation.98

Dang & Bright:
Fortunately, these norms of assertion don’t constrain science. We rightly tolerate the fact that it is, essentially, what you could politely call guesswork. Researchers must constantly be open to nature surprising them, and spread out over conceptual space, exploring whatever may be found. The trouble is that the general social esteem in which people hold science makes it natural for them to make an unhelpful assumption. That if scientific claims differ from the sort of claims each of us make every day, it is because the scientific ones have a better standing—better checked, have more evidence behind them, carry greater weight than our everyday assertions.128
