Before the advent of Modern Science, philosophy ruled over sciences. But, after the emergence of modern science, with the appearance of philosophers like Locke and Hume, empiricism which relied only on sense data became prevalent in most scientific circles. This was fortified by the advent of positivism of Aguste Comte which gave value only to the knowledge obtained from sensory experience. Thus, philosophy lost its status among scientists. But with the emergence of some schools of philosophy of science in the second half of the twentieth century, it became evident that all sciences are based on some general supra-scientific (metaphysical) principles. Then, some eminent physicists recognized the significant role of philosophy and several coalitions was formed between some eminent philosophers and physicists in several important universities of UK and USA, which has yielded fruitful results. With the revival of philosophy, religious studies, too, got momentum, and theists have used philosophical arguments to refute the challenges of atheists against theism.
