"Natural science, in its widest sense, aims at setting forth a coherent system of knowledge of how Nature works. The scientist is concerned not with the 'how we know' but with the 'what we know' of the objective world. He assumes from the outset that it is 'real', that it exists apart from the individual knower, is con...sistently measurable, and is a realm of law" (The Wings Of Faith p44-45).
