But, again, it is said that true reflection is marked by a certain characteristic bodily attitude, which bespeaks inner conflict and a search for adjustment. This contention seems to have little ground in fact. The puzzled, hesitating, undecided expression that is usually supposed to betray deep cogitation may in fact mean simply hesitation and bewilderment,--the need for thought, rather than its presence. The expression reveals a certain degree of incompetence and sluggishness in the individual concerned, and signifies a lack of wide-awakeness and responsiveness. A student puzzling over his algebra, a speaker extemporizing an argument, a ball-player using all his resources to defeat the enemy, have attitudes so unlike that no analysis could discover in them a common form of expression. And yet it would be madness to deny that thinking attends their various performances. There is, in short, no evidence from the side of bodily expression to indicate the presence in man of a special nervous faculty called reflection. Consider next the contention that the cue to thought is a puzzling situation, involving a problem. No problem, no thought; no thought, no problem. This may mean either that a man finding himself in a difficult situation uses all his energy and resource to escape from it, or, that he never concerns himself with abstract symbols except under the spur of necessity. The former meaning contains some truth, but the latter is what Dewey would call a 'dark saying.' If by 'thought' be meant that period of high activity of all the faculties which is only occasional, it is doubtless true enough that a problem is frequently needed to awaken it. Man is content to let life glide along with a minimum of effort; he cannot, if he would, long maintain the state of high activity here called 'thinking.' As a consequence of not thinking when he should, man frequently finds himself involved in situations requiring the exercise of all the energy and resource he possesses. But the really efficient 'thinker' is the man who keeps his eyes open, who sees ahead. He is not efficient merely because of the excellence of his established modes of response, but, more particularly, because he is alive and alert. His thinking is effective in preventing difficult situations, as well as in getting out of them.
