The question “what is reality?” is circular by demanding the answer from the questioner himself. If this question would have had a single true objective answer, then objectivity would have been the same as subjectivity, and similarity would thus have been the same as difference. An answer to this question thus requires fusion of similarity and difference.
The answer to this question is thus hidden in the distinctions that we make by conceptualization itself. We lose the answer in the moment we start looking for it.
Belief in an objective answer to this question, like cladistics and particle physics, also called realism, is thus vain. Never will it find the “things” it is looking for, like “the true tree of life” and “Higgs particle”. In an objective sense, these “things” are the same kind of things as Gods, and the question what Gods are belongs to theology. Science thus has to discard realism in order to liberate itself from theology.
We can answer the question “how does reality behave?”, but not the question “what is reality?”, because what it is do we decide, and for this reason, it actually can’t be anything objective. This question does thus belong to theology rather than to science.
