I would argue that the paragraph below from Hegel’s lessons on the Philosophy of History contains his entire philosophy concentrated in just a few (dense) sentences.
If we consider Spirit in this aspect — regarding its changes not merely as rejuvenescent transitions, i.e., returns to the same form, but rather as manipulations of itself, by which it multiplies the material for future endeavours — we see it exerting itself in a variety of modes and directions; developing its powers and gratifying its desires in a variety which is inexhaustible; because every one of its creations, in which it has already found gratification, meets it anew as material, and is a new stimulus to plastic activity. The abstract conception of mere change gives place to the thought of Spirit manifesting, developing, and perfecting its powers in every direction which its manifold nature can follow. What powers it inherently possesses we learn from the variety of products and formations which it originates. In this pleasurable activity, it has to do only with itself. As involved with the conditions of mere nature — internal and external — it will indeed meet in these not only opposition and hindrance, but will often see its endeavours thereby fail; often sink under the complications in which it is entangled either by Nature or by itself. But in such case it perishes in fulfilling its own destiny and proper function, and even thus exhibits the spectacle of self-demonstration as spiritual activity.
