We are often told that science proceeds on the basis of an underlying 'methodological naturalism'. Not so, to my mind. It is dominated today by philosophical naturalism, but it depends on methodological (Christian) theism to make the reliable presumption that the universe is amenable to rational examination and that our rationality is congruent with the nature of the universe. For these reasons science flowered in the soil of modern Christian thought (that typically took Genesis 1 seriously). I think we are seeing science under attack today, with the shrill dominance of 'critical theory' so called, and a growing 'identity' based subjectivism a growing undercurrent in all cultural streams. Both turn their back on the idea of rational examination and methodological objectivism.
