Abstract

Clearly, the world of nature is continually in a state of change and evolution. All of us experience such changes in our daily life; for example, we see that a plant rises from under the soil, grows bigger, becomes green, and finally dries out and turns into soil. Even solid things are not immune against such changes and evolutions, and older phenomena continually are replaced by newer ones through physical and chemical interactions.Therefore, the element of change in phenomena in an evident and undeniable fact; however, there are some serious debates among philosophers and thinkers regarding the philosophical interpretation and explanation of this change. Some of the controversies in this respect are as follows:Does this change occur in the form of "generation and corruption", i.e. in a sudden and discontinuous way, or in the form of a motion, i.e. gradually and continuously? How inclusive is this change? Does motion occur only in accidents and phenomena or does it also take place in the substance or essence of things? Is this change in the form of dressing after undressing, i.e. corruption and generation, or is it in the form of dressing after dressing, i.e. is the object continually in the state of becoming and moving from potency to actuality? This paper examines and criticizes the theories of philosophers and thinkers on motion
