Now, the effect of absentmindedness may gather strength in its turn.  There is a general law, the first example of which we have just encountered, and which we will formulate in the following terms:  when a certain comic effect has its origin in a certain cause, the more natural we regard the cause to be, the more comic shall we find the effect.  Even now we laugh at absentmindedness when presented to us as a simple fact.  Still more laughable will be the absentmindedness we have seen springing up and growing before our very eyes, with whose origin we are acquainted and whose life-history we can reconstruct.  To choose a definite example:  suppose a man has taken to reading nothing but romances of love and chivalry.  Attracted and fascinated by his heroes, his thoughts and intentions gradually turn more and more towards them, till one fine day we find him walking among us like a somnambulist.  His actions are distractions.  But then his distractions can be traced back to a definite, positive cause.  They are no longer cases of absence of mind, pure and simple; they find their explanation in the presence of the individual in quite definite, though imaginary, surroundings.  Doubtless a fall is always a fall, but it is one thing to tumble into a well because you were looking anywhere but in front of you, it is quite another thing to fall into it because you were intent upon a star.  It was certainly a star at which Don Quixote was gazing.  How profound is the comic element in the over-romantic, Utopian bent of mind!  And yet, if you reintroduce the idea of absentmindedness, which acts as a go-between, you will see this profound comic element uniting with the most superficial type.  Yes, indeed, these whimsical wild enthusiasts, these madmen who are yet so strangely reasonable, excite us to laughter by playing on the same chords within ourselves, by setting in motion the same inner mechanism, as does the victim of a practical joke or the passer-by who slips down in the street.  They, too, are runners who fall and simple souls who are being hoaxed—­runners after the ideal who stumble over realities, child-like dreamers for whom life delights to lie in wait.  But, above all, they are past-masters in absentmindedness, with this superiority over their fellows that their absentmindedness is systematic and organised around one central idea, and that their mishaps are also quite coherent, thanks to the inexorable logic which reality applies to the correction of dreams, so that they kindle in those around them, by a series of cumulative effects, a hilarity capable of unlimited expansion.
