Unhappily for himself and for Spain, he wanted the singleness of purpose required by a ruler who would devote himself to organization, and also the combination of firmness with temper needed for dealing with his nobles.
He found expression in so many ways, and was apparently so inexhaustible in his resources, that his very versatility and the ease with which he gave expression to his thought sometimes stood in the way of a recognition of his large, simple political ideality and the singleness of his moral sight.
Singleness of purpose, and relentless vigour in the execution of the purpose, were the qualities necessary to the conduct of the vast enterprise of subduing the Confederacy.
He traces this opposition into the forms in which it appears in the social life of mankind (as, e.g., in the difficulty of reconciling the conflicting claims of individual self-development and self-culture and social service), and finds " a hidden root of insincerity and hypocrisy beneath all morality " (p. 243), inasmuch as it is not possible to pursue any one type of ideal without some departure from singleness of purpose.
His singleness of purpose, personal independence and indomit able energy enabled him to achieve triumphs that to others seemed impossible.
