230 UNIVERSAL EVOLUTION 



LANGUAGE OF THE EMOTIONS. All the emotions can be 

 expressed without articulate speech. Laughter is the 

 expression of joy, weeping of grief, smiling of pleasure, 

 bodily attitude of anger or fear. These emotions are, 

 more or less, expressed by the muscles of the face. 



In fact, in a broad sense, the signs of life are the 

 marks of thought. When the human senses become 

 acute enough, they will perceive every thought in an- 

 other, by its physiological marks. "It is right then 

 to say that what we do depends upon what we are; 

 but it is necessary to add, that we are, to a certain 

 extent, what we do, and that we are creating ourselves 

 continually. ' ' ( Bergson. ) 



Should these physiological manifestations be prevented, 

 in any way, as by pathological conditions, then there 

 would be no thought; and, that interference with them, 

 in any degree, would in the same degree lessen the co- 

 herency, and perspicuity of the thinking. If all the 

 data of consciousness could be enumerated from the 

 center of attention at any moment to the thousand 

 things in the margin, or subattentive aurora of it, it 

 would be found, that all are objective, and come through 

 the senses. The consciousness of one, deprived of every 

 sense except touch, would be found to be made up of 

 sensations coming from the environment, that act only 

 on that sense. Should that also be taken away there 

 would be no consciousness, and perhaps no life. The 

 word function explains all psychical phenomena. 



BASIS OF THOUGHT. It will be found, also, that the 

 basis of thought is physical necessity, or self, or race 

 preservation. Why does the twining vine grow its 

 first two joints rigid, and the third so mobile that it will 

 vibrate in a circle, seeking an object round which it 

 can twine? Or, why does the rhizopod contract, and
