Ex: One has to believe something to produce a hypothesis, the hypothesis provides an artificial framework (paradigm). Tests are made within this paradigm to further the hypothesis to theory or to dis regard it. Back to the beginning, the hypothesis was based on a belief-bias that something should "work" a certain way. The logos was built upon that frame work so therefore isn't science a belief system almost comparable to religion.
