Dialogic approach to the history of philosophy demonstrates discursive return to several fundamental ideas that contradict one another. The art of a philosopher turns the ideas into concepts that either reproduce or assemble certain senses into something universal. The concepts are subjective to the limit, and they change an individual who thinks something over: they are not ready waiting, they must be created, and they are nothing without the 'creator's signature'. This turns a philosophy historian into a co-creator of texts. Reconstruction of philosophic concepts from this point of view shows, that a very interesting dialogue between Heraclitus and Parmenidus could have taken place. From the standpoint of regarding philosophy as the history of problems the fact is significant, that the concepts, created by them, are the examples (ways) of overcoming primary non-ruggedness of creative and conceptual thinking together with witnessing of their non-reduction towards images. Parmenidus was among the first ones to propose an idea of logical evidence, separating mind from conjecture, as well as logical thinking from the creatively sensual one, having formulated principles of identity and non-contradiction. Heraclitus gave attention to phenomenal existence, which is always in an uninterrupted and contradictory movement of establishment, owing to that it harmonizes contradictions in fleeting identities. In that thought, Hegel perceived the first certain definition of establishment, which is, at the same time, the first authentic definition of a thought, like the beginning of philosophy was seen in 'existence exists, non-existence does not exist' of Parmenidus.
