This means that he must give up the idea of educating himself.

It is only by turning his back on history, on literature, on philosophy, on music, on art, that he can hope to meet the exacting and ever-growing demands which Science makes on those who desire to be initiated into its mysteries.

To say that when he has "taken his degree" he is only half-educated, is greatly to over-estimate the formative influence of his highly specialised training.

A sense has undoubtedly been developed in him, an instinct has been awakened, one or two of his mental faculties have been vigorously cultivated; but his training has been the reverse of humanising; and as his studies and his consequent attitude towards Nature have been essentially _analytical_, he may, in the absence of those correctives which his compulsory specialising has withheld from him, have learned to regard the dead side of things as the real side,--a conception which, if it mastered him, would materialise his whole outlook on life.
The case of the "humanist" is different.

The subjects which he studies appeal to many sides of his being; and if he could respond to their appeal, they might do much for his mental and spiritual development.
