Disagree. At least within the sciences, the strength of the arguments the professor put forth rely on how well they are founded. Think derivation of e.g. newtonian gravitational theory as an inverse square law, which is justified when one considers some conserved quantity (like energy) being evenly radiated outwards from a point-source in space. Another example: the formulas of special relativity, which relies on the axiom stating that the speed of light is the same for all inertial observers, ref. the Michelson-Morley experiment. Special relativity would not make much sense unless this axiom is already shown to be a real and observable phenomenon. If, instead of referring to Michelson-Morley, a professor told students in a packed auditorium, “god willed the speed of light to be the same for all observers”, he would be laughed right out of there. So no, I strongly disagree with your assertion.
