If this work has any value, it consists in two things: the first is that thoughts are expressed in it, and on this score the better the thoughts are expressed—the more the nail has been hit on the head—the greater will be its value.-Here I am conscious of having fallen a long way short of what is possible. Simply because my powers are too slight for the accomplishment of the task.- May others come and do it better.
On the other hand the truth of the thoughts that are here communicated seems to me unassailable and definitive. I therefore believe myself to have found, on all essential points, the final solution of the problems. And if I am not mistaken in this belief, then the second thing in which the value of this work consists is that it shows how little is achieved when these problems are solved.
But this book has no pretensions either to his obscurity or to his profundity.
