We have already remarked by way of preparation that the Notion of true dialectic is to show forth the necessary movement of pure Notions, without thereby resolving these into nothing; for the result, simply expressed, is that they are this movement, and the universal is just the unity of these opposite Notions. We certainly do not find in Plato a full consciousness that this is the nature of dialectic, but we find dialectic itself present; that is, we find absolute existence thus recognized in pure Notions, and the representation of the movement of these Notions. What makes the study of the Platonic dialectic difficult is the development and the manifestation of the universal out of ordinary conceptions. This beginning, which appears to make knowledge easier, really makes the difficulty greater, since it introduces us into a field in which there is quite a different standard from what we have in reason, and makes this field present to us; when, on the contrary, progression and motion take place in pure Notions alone, the other is not remembered at all. But in that very way the Notions attain greater truth. For otherwise pure logical movement might easily appear to us to exist on its own account, like a private territory, which has another region alongside of it, also having its own particular place. But since both are there brought together, the speculative element begins to appear as it is in truth; that is, as being the only truth, and that, indeed, through the transformation of sensuous opinion into thought. For in our consciousness we first of all find the immediate individual, the sensuous real; or there are also categories of the understanding which are held by us to be ultimate and true. But contrasted with merely external reality, it is rather the ideal that is the most real, and it was Plato who perceived that it was the only real, for he characterized the universal or thought as the true, in opposition to what is sensuous.
