In the case of various kinds ...

In the case of various kinds of knowledge, we find that what in former days occupied the energies of men of mature mental ability sinks to the level of information, exercises, and even pastimes for children; and in this educational progress we can see the history of the world's culture delineated in faint outline.

Quotes from the same author

Everything that from eternity has happened in heaven and earth, the life of God and all the deeds of time simply are the struggles for Spirit to know Itself, to find Itself, be for Itself, and finally unite itself to Itself; it is alienated and divided, but only so as to be able thus to find itself and return to Itself...As existing in an individual form, this liberation is called 'I'; as developed to its totality, it is free Spirit; as feeling, it is Love; and as enjoyment, it is Blessedness.

...if the fear of falling into error is the source of a mistrust in Science, which in the absence of any such misgivings gets on with the work itself and actually does know, it is difficult to see why, conversely, a mistrust should not be placed in this mistrust, and why we should not be concerned that this fear of erring is itself the very error.

The beginning of religion, more precisely its content, is the concept of religion itself, that God is the absolute truth, the truth of all things, and subjectively that religion alone is the absolutely true knoweldge.

The True is the whole. But the whole is nothing other than the essence consummating itself through its development. Of the Absolute it must be said that it is essentially a result, that only in the end is it what it truly is; and that precisely in this consists its nature, viz. to be actual, subject, the spontaneous becoming of itself.

For us, mind has nature for its premise, being nature's truth and for that reason its absolute prius. In this truth nature has vanished, and mind has resulted as the idea arrived at being-for-itself, the object of which, as well as the subject, is the concept. This identity is absolute negativity, for whereas in nature the concept has its perfect external objectivity, this its alienation has been superseded, and in this alienation the concept has become identical with itself. But it is this identity therefore, only in being a return out of nature.
