…it can hardly be over-exaggerated that speculative thinking is always drawn from the necessities of the time, that it is always practical, that it always shifts with the interests of the times, with the changes of social, economic, and political conditions, and finally, that it is vain to hope to find an eternal, fixed, and immutable system of philosophy, and still hope for progress. A fixed system is applicable only to a dead society.
