Abstraction, definition of, 77 ; many ma- 

 terial ideas cease, or become weaker in, 

 77, 140 

 Action, muscular, animal when excited 

 by nerves, 163; from external im- 

 pressions and their direct nerve-ac- 

 tions, 452-465 ; from internal non- 

 conceptional impressions, 507 ; may 

 be a sentient action or a nerve action, 

 or both, 514 ; nature of investigated, 

 161, 380; effected solely through 

 nerves, 388 

 Action, reflex, see Reflexion, and Im- 

 pressions, external and internal. 

 Actions, animal, see Animal actions. 

 Actions, sentient, defined, 6 ; are direct 

 and indirect, 97-110; the conceptive 

 force co-operates in, 111; how pro- 

 duced, 112; a conceptional impression 

 necessary to, 123 ; when produced 

 directly by external sensations, 129; 

 when produced by conceptions, 130 ; 

 chai'acter of those excited by cerebral 

 impressions, 133 ; when produced by 

 external sensations, how prevented, 

 134 ; when caused by spontaneous 

 conceptions, hindrances to, 136, 138 ; 

 when produced by external sensations, 

 how enfeebled, or prevented, 139 ; 

 occur in the oesophagus and intestinal 

 canal, 170; occur in the stomach, 

 174 ; in the liver, 175 ; in the kidneys, 

 176; in the urinary bladder, ib.\ in 

 the organs of the external senses, 177 ; 

 in the sexual organs, 178 ; when not 

 direct results of the external sensa- 

 tions, 181 ; when at the same time 

 nerve-actions, 183, 363 ; how influ- 

 enced by the consciousness of an im- 

 pression,184,ii; from other conceptions, 

 often confounded with those from ex- 

 ternal sensations, 185 ; of agreeable 

 and disagreeable external sensations, 

 195 ; of gratification, 197 ; of pain, 

 198 ; developed even in the non-mus- 

 cular membranes, 208 ; of external 



Actions {continued) 



sensations in the heart, stomach, &c., 

 204-218; the incidental [zufallig], 

 219-224; the subordinate, 225; the 

 co-ordinate, 227 ; of imaginations, see 

 Imaginations ; of the memoiy, 238 ; 

 of the foreseeings, see Foreseeings ; of 

 the sensational desires and aversions, 

 255 ; of the sensational propensities 

 and emotions, 260 ; of the instincts, 

 281-292; of the passions, 306-329; 

 of the intellectual conceptions, 330; 

 may all be produced without brain, or 

 mind, or conceptions, 367 ; transfor- 

 mation of, into nerve-actions, or vice 

 versa, 367, 368 ; often result from 

 direct nerve-actions of external im- 

 pressions on the muscles, 448 ; substi- 

 tution of, for nerve-actions, 580-593 

 Affections, 91 

 Affectentriebe, the instinctive passions, 



296-304 

 Afferent and efferent fibrils in the same 

 nerve, doctrine of, 127 note, 486- 

 488 

 Age, old, its phenomena, 701 

 Ahndungen, 73. See Forebodings. 

 Albinus, his doctrine of the anatomical 

 distinctness of the nerve-fibrils anti- 

 cipating Miiller, 39 note; MSS. of, in 

 possession of Sir W. Hamilton, ib. 

 Anger, always a passion, 301 ; a de- 

 pressing one, 322 ; its sentient actions 

 how composed, ib. ; its union with 

 revenge, 324 ; the special changes its 

 sentient actions produce, 325 ; means 

 of controlling, 326 ; its sentient ac- 

 tions may be induced by the vis 

 nervosa only, 572 

 Animal, a purely sensational, see Sensa- 

 tional animal. 

 Animal, a reasoning, see Reasoning ani- 

 mal. 

 Animal, a sentient, see Sentient animal. 

 Animal, an insentient, see Insentient 

 animal.
