What a weariness it is to look back over the twenty odd volumes of the 'Journal of Speculative Philosophy' and see Harris's mind wholly filled by that one conception of self-determination--everything to be thought as 'part of a system'--a 'whole' and '_causa sui_.'--I should like to see such an idea get into the head of Edison or George Westinghouse."
