As the essence of Matter is Gravity, so, on the other hand, we may affirm that the substance, the essence of Spirit is Freedom. - Georg Wilhelm Friedrich Hegel

The only Thought which Philosophy brings with it to the contemplation of History, is the simple conception of Reason; that Reason is the Sovereign of the World; that the history of the world, therefore, presents us with a rational process.

Man is an animal, but even in his animal
functions, he is not confined to the implicit, as the animal is; he
becomes conscious of them, recognizes them, and lifts them, as,
for instance, the process of digestion, into self-conscious science.
In this way man breaks the barrier of his implicit and immediate
character, so that precisely because he knows that he is an animal,
he ceases to be an animal and attains knowledge of himself as
spirit.

It is because the method of physics does not satisfy the comprehension that we have to go on further.
