Jordan Peterson, while interviewing British theologian, academic and author Dr. Nigel Biggar (under the title “Separating Good from Evil in the British Empire“), gives a brief lecture on the five metaphysical presumptions of science. He says (link prompted):

They are metaphysical presumptions which you have to accept before you can operate as a scientist.

You have to believe there is a logos or logic in the objective world. Youi have to believe there is an objective world. You have to believe that that logic is apprehensible. You have to believe that apprehending that logic is a moral good. Because otherwise why would you bother? And then you have to believe that truth in relation to that apprehension is the most important orienting principle.

Those are all metaphysical presumptions. I actually think they are metaphysical presumptions that are derived from Christianity itself, which is why science emerged in Europe and not elsewhere.
