The Romans show by such a phrase as _animum adjicere_, and numerous proverbs and synonyms, that they had learned to bend their attention energetically.

They were good listeners, therefore keen observers.
Learning to control or strengthen the Will is closely allied to developing Attention and Interest, and for reasons which will soon be apparent, I will first consider the latter, since they constitute a preparation or basis for the former.

And as preliminary, I will consider the popular or common error to the effect that everyone has alloted to him or to her just so much of the faculty of attention or interest as it has pleased Nature to give--the same being true as regards Memory, Will, the Constructive or Artistic abilities, and so on--when in very truth and on the warrant of Experience all may be increased _ad infinitum_.

Therefore, we find ignorant men complacently explaining their indifference to art and literature or culture on the ground that they take no interest in such subjects, as if interest were a special heaven-sent gift.

Who has not heard the remark, "He or she takes such an _interest_ in so many things--I wish that I could." Or, as I heard it very recently expressed, "It must be delightful to be able to interest one's self in something at any time." Which was much the same as the expression of the Pennsylvania German girl, "_Ach Gott_! I wisht I hat genius und could make a pudden!" No one can be expected to take an interest at once and by mere will in any subject, but where an earnest and serious Attention has been directed to it, Interest soon follows.
