matter for his activity, nor in the forces necessary to become himself a creator in his sphere. This vocation is yours also, Julius; when you have recognized this you will never have a thought of complaining of the limits that your desire of knowledge cannot overstep. When you have arrived at this conviction I expect to find you wholly reconciled to me. You must first know fully the extent of your strength before you can appreciate the value of its freest manifestation. Till then, continue to be dissatisfied with me, but do not despair of yourself. ON THE CONNECTION BETWEEN THE ANIMAL AND THE SPIRITUAL NATURE IN MAN. "It behooves us to clearly realize, as the broad facts which have most wide-reaching consequences in mental physiology and pathology, that all parts of the body, the highest and the lowest, have a sympathy with one another more intelligent than conscious intelligence can yet, or perhaps ever will, conceive; that there is not an organic motion, visible or invisible, sensible or insensible, ministrant to the noblest or to the most humble purposes, which does not work its appointed effect in the complex recesses of the mind, and that the mind, as the crowning achievement of organization, and the consummation and outcome of all its energies, really comprehends the bodily life."--MAWDESLEY, Body and Mind. "It is an indisputable truth that what we call the material world is only known to us under the forms of the ideal world, and, as Descartes tells us, our knowledge of the soul is more intimate and certain than our knowledge of the body."--HUXLEY. INTRODUCTION. S 1. Many philosophers have asserted that the body is, as it were, the prison-house of the spirit, holding it only too firmly to what is earthly, and checking its so-called flight towards perfection. On the other hand, it has been held by another philosophic school that knowledge and virtue are not so much an end as a means towards happiness, and that the whole perfection of man culminates in the amelioration of his body.
