It is rather difficult to give a concise definition of attention, although we know well enough what is meant. It may be likened to a state of concentrated or focussed consciousness as opposed to the diffused, or, again, it may be considered as the definite direction of mind towards an object. There are three kinds of attention, and the first, which we may just mention in passing, is spontaneous attention. We attend spontaneously to claps of thunder and sudden noises because we cannot help it; but in this type lies no educational interest.
