excogitate

It is always peculiarly fascinating, therefore, to subject to direct verification by observation, that is, to render palpable to the senses, something which we have only theoretically excogitated or theoretically surmised.

Did ever a human being excogitate such blasphemous nonsense?

Nature in a mirror is just nature, not nature thought out, excogitated, turned to human uses, interpreted in human words.

By the time that I had excogitated all this, my feet had visited many square yards of palace, comprising bed-room, banqueting-room, chief lady's room, chapel, and so on.

This is the most perfect form of absolutism ever yet excogitated in any man's brains.
