However, it is not unusual to realize the emphasis of scientific thought as rationally justifiable. Certainly, the dynamics of scientific thought throughout history has not been indifferent to other possibilities of epistemological construction. We cannot escape the facts： Science needs linguistic devices to strengthen its principles and criteria for validation. The aim of this paper is to answer, based on a new conception of metaphor, under what conditions metaphor can be a ＂physical metaphor＂ and the extent to which the symbolism in general brings a special light gain of sense to the understanding of physical reality that surrounds us.展开更多
