states (that is, in the spheres of Ohjective Psychology 

 and Neurology), but also in regard to the whole system 

 of Natural Knowledge. Thus, as regards vital, mental, 

 magnetic, electric, thermal, chemical, mechanical, and all 

 other phenomena, our actual present ' knowledge ' is 

 made up of a closely-interwoven potential hut intelligible 

 fabric derived from actually existent, from remembered, 

 described, or inferred Conscious States or relations be- 

 tween them, together with inextricably intermixed and 

 more or less ' legitimate inferences ' therefrom. 



Our knowledge of what is called Objective Psychology, 

 as well as our knowledge of the relation of subjective 

 states generally to the activity of the Nervous System, as 

 deduced from its Anatomy, Physiology, and Pathology 

 (the knowledge, that is, which contributes so largely to 

 make up what we know concerning Mind, or mental 

 phenomena) stands, therefore, on precisely the same 

 foundation as our knowledge of Magnetism — that is of the 

 magnetic phenomena presented by different forms of iron. 

 The word ' Magnetism ' is one which has come into use 

 in much the same way as the word * Mind,' although it 

 is true that the connotation of the latter is wider in kind 

 and degree, since under it we include not only what are 

 considered ' legitimate inferences ' from conscious states 

 (our only sources of knowledge concerning Magnetism), 

 but also these very conscious states themselves. It is on 

 this latter ground only — though of course it is one of 

 fundamental importance — that our knowledge of ' Mind ' 

 differs from what we know generally in regard to all 

 other natural phenomena. 



From a basis of agreement, therefore, as to the acknow- 

 ledged insufficiency of the direct revelations of Conscious- 

 ness in any branch of natural knowledge, it seems to 

 the writer incontestible that the same kind of evidence as
