298 ON LIFE AND ORGANISATION. 



currents in the cells and fibres of the brain and spinal mar- 

 row ; and of physical currents in the spinal marrow and brain 

 inducing sensation — it would be equally unphilosophical to 

 deny, as to assert, that psychical power and physical force do 

 immediately influence one another in the living organised 

 body ; or to assume, as an element in physiological research, 

 that the indwelling or containing psyche is the source of or- 

 ganic form, or that it influences chemico-physical forces to 

 that effect. 



I therefore state, provisionally, that the corporeal structure 

 of the organised being is co-ordinated with the specific en- 

 dowments of its psyche, so that they act and react harmoni- 

 ously. 



The psyche is latent in the plant, as it is in the higher 

 animals during its embryo condition. 



In the animal series, the psyche, distinct for each indivi- 

 dual, and specific for each species, is more highly endowed, 

 according to the elevation of the animal in the scale. 



The psyche regulates the actions and habits of the animal 

 in accordance with its corporeal structure ; and the conditions 

 of its existence has a code of laws, to which we apply the 

 term instinct. 



The psychological constitution of the animal, and its 

 peculiar form of consciousness, are conditioned by the in- 

 stinct. 



It is unphilosophical to entertain the epiestion in regard 

 to the mortality of the psyche of the brute. 



Physiological considerations, psychological and philoso- 

 phical induction, and the precise statements of Kevelation, 

 prove that man, in addition to his body, with its chemico- 

 physical properties, and his psyche, which is the co-ordinated 

 form of his organisation, and the source of his instincts, 

 appetites, and passions, possesses also his pneurna, which con- 

 stitutes his personality, is the essence of his peculiar self-
