parts: they were painful when there was little air, and when the blood was torpid and thick.[193] [Footnote 188: Diogen. Apoll. Fr. vii. ch. 48, Panz. The description of the veins given by Diogenes is preserved in Aristotel. Hist. Animal, iii. 2: yet seemingly only in a defective abstract, for Theophrastus alludes to various opinions of Diogenes on the veins, which are not contained in Aristotle. See Philippson, [Greek: U(/lê a)nthrôpi/nê], p. 203.] [Footnote 189: Plutarch, Placit. Philos. iv. 5. [Greek: E)n tê=| a)rtêriakê=| koili/a| tê=s kardi/as, ê(/tis e)sti\ kai\ pneumatikê/]. See Panzerbieter's commentary upon these words, which are not very clear (c. 50), nor easy to reconcile with the description given by Diogenes himself of the veins.] [Footnote 190: Plutarch, Placit. Philosoph. iv. 18. Theophrast. De Sensu, s. 39-41-43. [Greek: Kritikô/taton de\ ê(donê=s tê\n glô=ttan; a(palô/taton ga\r ei)=nai kai\ mano\n kai\ ta\s phle/bas a(pa/sas a)nê/kein ei)s au)tê/n.]] [Footnote 191: Plutarch, Placit. Philosoph. iv. 16; Theophrastus, De Sensu, s. 40.] [Footnote 192: Theophrast. De Sensu, s. 42.

The same opinion--that sensation, like thought, is a mental process, depending on physical conditions--is ascribed to Strato (the disciple and successor of Theophrastus) by Porphyry, De Abstinentiâ, iii. 21. [Greek: Stra/tônos tou= phusikou= lo/gos e)sti\n a)podeiknu/ôn, ô(s ou)de\ ai)stha/nesthai to para/pan a)/neu tou= noei=n u(pa/rchei. kai\ ga\r gra/mmata polla/kis e)piporeuome/nous tê=| o)/psei kai\ lo/goi prospi/ptontes tê=| a)koê=| dialantha/nousin ê(ma=s kai\ diapheu/gousi pro\s e(te/rous to\n nou=n e)/chontas--ê(=| kai\ le/lektai, nou=s o(rê= kai\ nou=s a)kou/ei, ta)/lla kôpha\ kai\ tuphla/.] The expression ascribed to Diogenes by Theophrastus--[Greek: o( e)nto\s a)ê\r, mikro\n ô)\n mo/rion _tou= theou=_]--is so printed by Philippson; but the word [Greek: theou=] seems not well avouched as to the text, and Schneider prints [Greek: thumou=]. It is not impossible that Diogenes may have called the air God, without departing from his physical theory; but this requires proof.] [Footnote 193: Theophrastus, De Sensu, s. 43-46; Plutarch, Placit. Philos. v. 20. That moisture is the cause of dulness, and that the dry soul is the best and most intelligent--is cited among the doctrines of Herakleitus, with whom Diogenes of Apollonia is often in harmony. [Greek: Au)/ê psuchê\ sophôta/tê kai\ a)ri/stê.] See Schleiermach. Herakleitos, sect. 59-64.] [Side-note: Kosmology and meteorology.]
