But the drawback that attaches to this Philosophy is that the ultimate appeal—even in modern times—is made to the fact that men are constituted such as they are by nature, and with this Cicero is very free. Here the moral instinct comes into question, only under the name of feeling; Religion now rests not on what is objective but on religious feeling, because the immediate consciousness of God by men is its ultimate ground. Cicero makes copious use of the _consensus gentium_; in more modern times this appeal has been more or less left alone, since the individual subject has to rest upon himself. Feeling is first of all laid hold of, then comes reasoning from what is given, but in these we can appeal to what is immediate only. Independent thought is certainly here advanced; the content too, is taken from the self; but we must just as necessarily exclude this mode of thinking from Philosophy. For the source from which the content is derived is of the same description as in the other cases. Nature is the source in finite sciences, and in Religion it is Spirit; but here the source is in authority; the content is given and the act of worship removes but momentarily this externality. The source of popular Philosophy is in the heart, impulses and capacities, our natural Being, my impression of what is right and of God; the content is in a form which is of nature only. I certainly have everything in feeling, but the whole content is also in Mythology, and yet in neither is it so in veritable form. The laws and doctrines of Religion are that in which this content always comes to consciousness in a more definite way, while in feeling there still is intermingled the arbitrary will of that which is subjective. 3. COMMENCEMENT OF PHILOSOPHY AND OF ITS HISTORY. Now that we have thus defined the Notion of Philosophy to be the Thought which, as the universal content, is complete Being, it will be shown in the history of Philosophy how the determinations in this content make their appearance little by little. At first we only ask where Philosophy and its History begin. _a. Freedom of Thought as a first condition._
