Every subsequent account of time, including Bergson's, has been essentially determined by it. When we analyse the Aristotelian conception, it will likewise become clear, as we go back, that the Kantian account of time operates within the structures which Aristotle has set forth; this means that Kant's basic ontological orientation remains that of the Greeks, in spite of all the distinctions which arise in a new inquiry.
The question of Being does not achieve its true concreteness until we have carried through the process of destroying the ontological tradition. In this way we can fully prove that the question of the meaning of Being is one that we cannot avoid, and we can demonstrate what it means to talk about 'restating' this question.
In any investigation in this field, where 'the thing itself is deeply veiled' one must take pains not to overestimate the results. For in such an inquiry one is constantly compelled to face the possibility of disclosing an even more primordial and more universal horizon from which we may draw the answer to the question, "What is 'Being'?" We can discuss such possibilities seriously and with positive  results only if the question of Being has been reawakened and we have arrived at a field where we can come to terms with it in a way that can be controlled.
¶ 7. The Phenomenological Method of Investigation
In provisionally characterizing the object which serves as the theme of our investigation (the Being of entities, or the meaning of Being in general), it seems that we have also delineated the method to be employed. The task of ontology is to explain Being itself and to make the Being of entities stand out in full relief. And the method of ontology remains questionable in the highest degree as long as we merely consult those ontologies which have come down to us historically, or other essays of that character. Since the term "ontology" is used in this investigation in a sense which is formally broad, any attempt to clarify the method of ontology by tracing its history is automatically ruled out.
When, moreover, we use the term "ontology", we are not talking about some definite philosophical discipline standing in interconnection with the others. Here one does not have to measure up to the tasks of some discipline that has been presented beforehand; on the contrary, only in terms of the objective necessities of definite questions and the kind of treatment which the 'things themselves' require, can one develop such a discipline.
With the question of the meaning of Being, our investigation comes up against the fundamental question of philosophy.
