Aristotle's Metaphysics, "there Is A Problem

Metaphysics is interpreted as an ontology in respect of modern philosophy,and especially of the phenomenology. It is treated in two ways,that is,philologically and philosophically. The main subject of Metaphysics is the "question of being",in it,the core is ontology,aetiology is the methodology,then the ousiology and teleology are the development of the ontology . Then I discuss the debate about the question of being these recent years,and give a response .As the beginning of ontology,Parmenides's being(is)is one,is eternity underlying the motion,it struggles against destiny,so it should be considered as a priori of relations between man and world,and also as transcendence of the world . The ontology of Plato is about the being of Idea,the universal essence. The being of Aristotle has manifoldness on one hand,and has unity on the other hand,it is not unified as genus,but as analogy .It indicates absolute Being and beings in Aristotle's work. The ontology has being qua being as its object,and the core is substance. The substance is the first category and prime being. The key to the positive explication of substance lies in the settlement of the conflict between the concrete and the abstract,essence and individual. The meaning of "Being of beings" is expressed in the explanation of substance,which is explained through the essence and "this". As far as the essence implies concept of time,the substance means presence and act. "this" seems to be equivalent to "intuition of essence". There are three dimensions in "this",which are "I","here"and "now". These included almost all structure of the later ontology.This implies the concept of time,which makes substance to be understood as "presence",so Being obtains the constancy of "now",and is understood as presence . Being is considered in potency and actuality as act and realisation . In a word,I want to express clearly the difference between Being and beings,which was not distinctly said by Aristotle,and think Being absolute and transcendent. I reveal the timeness out of Being,and it shows the destiny of finitude of human being. The question of being is the care about the life .
