It would be superfluous to speak further of their logic any more than of their theory of judgments, which in part coincides with it, and in part is a grammar and a rhetoric; by it no real scientific content can be reached. For this logic is not, like Plato’s dialectic, the speculative science of the absolute Idea; but, as formal logic, as we saw above (p. 254), it is science as the firm, secure, unalterable comprehension of reasons, and stops short at the perception of the same. This logical element, whose essence consists pre-eminently in escaping to the simplicity of the conception to that which is not in opposition to itself nor falls into contradiction, obtains the upper hand. This simplicity, which has not negativity and content in itself, requires a given content which it may not abrogate—but consequently it cannot thus attain to a genuine “other” through itself. The Stoics have constituted their logic often in the most isolated fashion; the principal point that is established here is that the objective corresponds to thought, and they investigated this thought more closely. If in a manner it is quite correct to say that the universal is the true, and that thought has a definite content that must also be concrete, the main difficulty, which is to deduce the particular determination from the universal, so that in this self-determination it may remain identical with itself, has not been solved by the Stoics: and this the Sceptics brought to consciousness. This is the point of view most important in the philosophy of the Stoics; it thus showed itself in their physics also. 3. ETHICS. Since the theory of mind, the doctrine of knowledge, came before us in the investigation of the criterion, we have, in the third and last place, to speak of the morality of the Stoics, to which is due their greatest fame, but which does not rise above this formal element any more than what precedes, although it cannot be denied that in presenting it they have taken a course which seems very plausible to the popular conception, but which in fact is to a great extent external and empiric.
