Scientism.
Look, unlike so many others, I actually gave an answer.
The term "scientism" has historically been a pejorative term in the history of philosophy, and usually is used by figures who believe that a particular person is overstating either the power of science itself, or the power of certain aspects of science. However, when I use the term "scientism", I am basically referring to a philosophical position that the general best path to truth about reality is science and scientific thinking.
For example, if we are curious about the workings of language, while it is correct that we could attempt a philosophical inquiry, my claim is that we would probably really be better off engaging in an anthropological and psychological inquiry into how people use words, and how the human language is generated by the human mind, instead of introspection and intuition.
Basically, to give a rough overview of the underpinning assumptions involved here:
1) Many of our intuitions and introspections are a terrible guide to truth. We've seen this over the past throughout the history of philosophy. Despite thousands of years of arguments, in many cases, the growth of knowledge is not that powerful. Instead, we see philosophers going in a broad variety of very different directions across time, and very little resolution or hope for that, which leads outsiders to the field to dismiss it, and even leads some insiders to suggest that philosophy really doesn't progress. Even further, just as an empirical fact, both intuitions and introspections are unreliable when put under scientific study, as we see variation across the population in both factors, and even that intuitions and introspections can easily be modified by other thought experiments and experiences, etc.
2) Anything we know about the world is going to generally be a matter of empirics, or reason, and possibly a few approximations, and most things that would appear to be otherwise, like revelations, etc, are generally in unreliable categories.
3) Science, or math and science(if you really need the distinction) are sufficient to study most of the facts we know empirically or via reason about the perceived world. So, as the example I gave language. However, really any set of data can be explored scientifically if we have enough data, such as revelations, morality, culture, etc, etc.
The consequences of scientism are generally the following:
a) Hard-core naturalism. Scientific answers generally strongly tend to be strictly naturalistic answers. The reason for this is not necessarily clear, as there are many different views on why this is the case. One view is that science is strictly methodologically naturalist. Another is the science is loosely methodologically naturalist as a regard of no good supernatural answers being plausible. The last is that science is not methodologically naturalist, it's just that supernatural answers are generally implausible. Most people holding to scientism have no problem with this conclusion though, and a good number of them are in the second and third interpretation of science and naturalism, where they simply believe that an unpacked supernatural theory would fail by one or more explanatory metrics.
b) Certain lines of inquiry are irrevocably silenced. For instance, asking the question "What is the meaning of life?" no longer makes sense. Life can no longer be plausibility analyzed through intuitions and introspection, but rather life is simply a fact to be explained through biology and perhaps cosmology. The same extends for a lot of traditional philosophical questions.
c) A much clearer path to success in inquiry. While earlier philosophies had to include all of this impossible to figure out data from introspection and intuition, scientism strongly weights a particular approach, and one that has generally shown a relatively high chance of success in it's goals. Sure, we can argue that introspection and intuition cannot be ENTIRELY abolished, and all sorts of other issues, however, a good way to look at the framework is simple. We've tried many different intellectual approaches, and many of these approaches have been unsuccessful. Scientism is simply a reweighting of our epistemological tool-kit towards the methods that have best served the human growth of knowledge and that presumably will provide the most knowledge for our effort, without wasting our time with approaches that will provide no knowledge.
