“We realize, however, that all scientific laws merely represent abstractions and idealizations expressing certain aspects of reality. Every science means a schematized picture of reality, in the sense that a certain conceptual construct is unequivocally related to certain features of order in reality;”

— Ludwig von Bertalanffy

“The Reality? Is it then so certain that Life is made of four Absurdities?
Is it not far more certain that life is made up of Four Beauties
of Calmness, Joy, Harmony, Rhythm…
The truest reality.
And what of the expression of all this — Art?
Must Pandemonium and Ugliness ever stand for Strength?”

“The fact is that science itself must change, as it discovers that its net of evidence is equipped only to catch certain kinds of fish, and that it is constructed of webs of assumptions that can only hold certain varieties of reality, while others escape its bet entirely.”

“The 'physical' does not mean any particular kind of reality, but a particular kind of denoting reality, namely a system of concepts in the natural sciences which is necessary for the cognition of reality. 'The physical' should not be interpreted wrongly as an attribute of one part of reality, but not of the other; it is rather a word denoting a kind of conceptual construction, as, e. g., the markers 'geographical' or 'mathematical', which denote not any distinct properties of real things, but always merely a manner of presenting them by means of ideas.”

“We look upon economic theory as a sequence of conceptual models that seek to express in simplified form different aspects of an always more complicated reality.”

“Scientific models have all these connotations. They are representations of states, objects, and events. They are idealized in the sense that they are less complicated than reality and hence easier to use for research purposes. These models are easier to manipulate and "carry" than the real thing. The simplicity of models, compared with reality, lies in the fact that only the relevant properties of reality are represented.”
