Meaning
Hair; an individual hair, with plural often referring to the hair collectively.
Grammatical category: feminine noun.
Use in the book
The passage uses the accusative plural τρίχας of the boy’s fair hair. The changing stem explains why the form does not look exactly like the dictionary headword.
The plural controls feminine adjectives and pronouns throughout the analogy: the hairs appear white after coating and become white through old age. Tracking that agreement helps separate the hair itself from the whitening material applied to it.

Meaning
Thrix is a hair; its plural commonly denotes hair collectively.
Use in the book
The Timaeus describes birds as growing feathers in place of hair when certain human lives are refashioned. The contrast supplies a visible bodily sign of transformation. Hair’s role is therefore comparative: it marks the earlier human covering against the new avian one.

- In EmpedoclesB82 says that hair and the other listed coverings are “the same things.”

- A place to readHair is placed beside leaves, plumage, and scales.
Meaning
Τρίχες names hair in the comparison B82 makes with leaves, bird feathers, and scales. B67 describes men as more shaggy or hairy. The terms link a familiar surface growth both to cross-species comparison and to an account of sexual bodily difference.
Use in the book
B82 says that hair and the other listed coverings are “the same things.” Its boldness lies in finding continuity among forms normally classified by different organisms: a plant’s leaves, a bird’s feathers, and a hairy or scaled animal’s surface are brought under a common explanation. The verse does not offer the modern claim that these structures are anatomically identical in every respect. In the setting of a mixture theory, sameness concerns shared material or formative explanation while visible forms remain diverse.
B67 approaches hairiness through temperature. The warmer male-bearing region is followed by a description of men as darker and hairier. This ancient causal association belongs to the specific reproductive theory of that fragment. It should not be converted into a rule for modern individuals or used to validate bodily stereotypes.
The hedgehog’s bristles in B83 provide a vivid special case of surface growth. Their pointed, erect quality is explicitly described, but the poem as printed does not connect them by an argument to the particular temperature claim about men. Shared bodily vocabulary encourages comparison without making every explanation universal.

θρὶξ (thrix); ἐξ ἁπάντων (ex hapantōn)
Thrix is hair.
Orientation
At a Glance
- The wordThrix is hair.
- In this workThe critic says bone and hair would perceive because they too consist of all the elements.
- In this editionThe edition's prose says there would be “nothing to stop a hair from thinking.”
- A place to readPairs hair with bone in an inferred consequence of the elemental account of perception.
Meaning
Thrix is hair. The phrase “from all” refers in context to all the elements composing it. Theophrastus introduces hair as a bodily counterexample to a proposed explanation of perception, not as an independently detailed tissue recipe.
Use in the book
The critic says bone and hair would perceive because they too consist of all the elements. The point is not that they are blood, but that the general elemental condition invoked for cognition appears insufficiently specific. If possession of the constituents which recognize their counterparts is enough, an apparently nonperceiving bodily product meets that condition as well.
The example therefore complements rather than repeats the bloodless-animal objection. Bloodlessness challenges the privileged material medium; hair challenges the adequacy of elemental composition as such. It would be misleading to say Empedocles expressly taught that each hair thinks. The statement is Theophrastus's inferred consequence, used to demand a distinction among tissues, cognitive organs, and thinking animals. A broader account of the bodily parts may help contextualize it, but the printed paragraph supplies no response that resolves the difficulty.

Translation in this edition
The edition's prose says there would be “nothing to stop a hair from thinking.” The ancient sentence specifically says bone and hair would perceive; the extension to thinking follows the surrounding argument rather than that clause's verb alone.
