From men wholly without philosophy, who never looked heavenward, the more brutal land animals are derived, losing the round form of the cranium by the slackening and stopping of the rotations of the encephalic soul.

Ranked by relevance and common usage.
Keep "encephalic" when the sentence already sounds natural, when a synonym would add unintended emphasis, or when readers need the most familiar wording. A synonym should clarify or sharpen the message, not simply make the sentence look more varied.
If two options seem close, choose the one that best matches the audience and purpose of the sentence.
Choose a synonym only if it keeps the core idea of "encephalic" intact in the sentence you are editing.
Check whether the replacement sounds more formal, casual, emotional, technical, or forceful than the original word.
Read the full sentence after the swap. Keep the synonym only when the sentence becomes clearer or more precise.
Review note: Synonym lists are ranked with lexical data and reviewed for practical writing value. Use the comparison notes, sentence evidence, and source labels together; a high-ranking synonym can still be wrong when the audience, register, or grammar changes.
After choosing a replacement for "encephalic", read the sentence once for meaning and once for rhythm. The best synonym should feel natural in the full sentence, not only accurate in a word list.
If the synonym makes the sentence slower, vaguer, or more dramatic than intended, keep "encephalic" or choose a simpler alternative from the closest-match group.

The misfortune was that he could not find in himself any of the causes which resolve into insomnia; he had neither meningitis nor brain fever, nor anything that indicated a cerebral tumor; he was not anaemic; he ate well; he did not suffer with neuralgia, nor with any acute or chronic affection that generally accompanied the absence of sleep; he drank neither tea nor alcohol; and without this state of over-excitement of the encephalic centres, he might have said that he was in good health, a little thin, but that was all.
