1 50 FEELING, A MARK OF MIND. 



If, therefore, nerves are not directly concerned in the 

 operations in question, it is clear that the mind can only 

 influence them in a very indirect manner, and organs of 

 secretion cannot in any way be regarded as organs of the 

 mind, nor can their action be properly compared with the 

 action of the brain or any part of the nervous system. And, 

 lastly, I must point out that the word "organ" has been 

 nsed in different senses, and the definition that would apply 

 to a glandular structure like the liver, would not also apply 

 to the brain as the organ of the mind. 



Feeling is said to be the foremost and most unmistakable 

 mark of mind. But " feeling " is also stated to be an 

 attribute of animals and tissues which do not exhibit mental 

 endowments. Of feeling there are indeed different kinds. 

 The feeling of a man, the feeling of an amoeba, and \\\Q feeling 

 of a sensitive plant are, it may be said, properties (?) of 

 things that live, but there is little else common between 

 these forms of feeling.* 



Professor Bain at one time held that the organ of mind 



* Prof. Bain asserts that "the vegetable and mineral worlds are 

 devoid of feeling ;" but if he denies that some vegetable organisms^/, 

 he must admit that some animals are devoid of this endowment. The 

 conjunction of the vegetable with the mineral world is misleading, for 

 while the animal and vegetable worlds are very closely related, the 

 mineral world is absolutely separated from both, and has no "proper- 

 ties " in common with either. The term property, however, is not well 

 denned, and in scientific writings has been employed in more senses 

 than one. By some, mind has been regarded as a property of brain 

 matter, and the action of tissues and organs has been stated to be due to 

 the properties of the material particles of which they are composed. 

 Bain, however, speaks of the "property of the Intellect," which cannot 

 be a property of the same order as a property of matter that can be 

 weighed, measured, seen, and touched one is a material property, the 

 other is a different kind of property.
