I turn next to what has been said by Dr. Shadworth H. Hodgson, in his essay on “The Future of Metaphysic,” published in the _Contemporary Review_ for November, 1872. Remarking only, with respect to the agreements he expresses in certain views of mine, that I value them as coming from a thinker of subtlety and independence, I will confine myself here to his disagreements. Dr. Hodgson, before giving his own view, briefly describes and criticizes the views of Hegel and Comte, with both of whom he partly agrees and partly disagrees, and then {226} proceeds to criticize the view set forth by me. After a preliminary brief statement of my position, to the wording of which I demur, he goes on to say:― “In his _First Principles_, Part I, second ed., there is a chapter headed ‘Ultimate Scientific Ideas,’ in which he enumerates six such ideas or groups of ideas, and attempts to show that they are entirely incomprehensible. The six are:—1. Space and Time. 2. Matter. 3. Rest and Motion. 4. Force. 5. Consciousness. 6. The Soul, or the Ego. Now to enter at length into all of these would be an undertaking too large for the present occasion; but I will take the first of the six, and endeavour to show in its case the entire untenability of Mr. Spencer’s view; and since the same arguments may be employed against the rest, I shall be content that my case against them should be held to fail if my case should fail in respect to Space and Time.” I willingly join issue with Dr. Hodgson on these terms; and proceed to examine, one by one, the several arguments he uses to show the invalidity of my conclusions. Following his criticisms in the order he has chosen, I begin with the sentence following that which I have just quoted. The first part of it runs thus:—“The metaphysical view of Space and Time is, that they are elements in all phenomena, whether the phenomena are presentations or representations.”
