What is the name of the school of thought that holds "humans did it"?

Question

My world view is that there is no way to peek behind the curtains of the universe to reveal its truths-- whether spiritual, religious, or even scientific.

I don't think the word to describe this is Skepticism because whether or not I can be certain of all truths is not really the question I am trying to ask. It is irrelevant to me whether or not I can truly know that I and the things and around me exist. I simply recognize that all attempts to quantify the workings of the universe are man-made descriptive models that can, admittedly, be extremely accurate at predicting things but can never attain the stamp of universal truth.

The word I've been using to describe myself so far is Anthropocentric in an attempt to denote the idea that every piece of information or knowledge in the world is the product of human minds, but I feel as if Anthropocentrism additionally attributes a certain spiritual significance to humanity that I wish to avoid. I don't want to rule out the possibility that other organisms can develop and share their own systems of world-outlooks. My only admission is that only the ideas of humanity are the ones we have access to so far.

Is there a word for the school of thought and/or philosophy that holds "humans made it all up," or, more broadly, "citizens/inhabitants of the universe made it all up"?

Answer 1

I should say that a variety of phenomenalism describes your position. Measure your views against the following possibilities :

Let us begin by distinguishing several views that have borne the label 'phenomenalism' and noting which of them Lewis held. First, there is analytical phenomenalism:

Statements about physical objects are equivalent in meaning to statements exclusively about sense data (or: ways of appearing, etc.)

When I speak of phenomenalism without qualification, this is the doctrine I shall have in mind. Next, there is ontological phenomenalism:

Physical objects are identical with collections or families of actual and possible sense data.

Ontological phenomenalism is sometimes regarded as merely a "material mode" version of analytical phenomenalism, but I shall regard it as a thesis in its own right.

Lewis also used the term 'phenomenalism' in connection with two other views, which I shall name after their most distinguished proponents. The first of these is Kantian phenomenalism:

We know things only as they appear to us, not as they are in themselves.

And the other is Berkeleian phenomenalism:

Physical objects are existentially mind-dependent (i.e., they exist only when perceived).

(James van Cleve, 'C. I. Lewis' Defense of Phenomenalism', Philosophy and Phenomenological Research, Vol. 41, No. 3 (Mar., 1981), pp. 325-332 : 325.)

Though the statement of Kantian phenomenalism is brief and in need of elaboration and refinement, it does seem to capture the 'world view' you describe at starting.
