62.  There are sundry facts which alike illustrate this, and are explained by it.  Climax is one of them.  The marked effect obtained by placing last the most striking of any series of images, and the weakness—­often the ludicrous weakness—­produced by reversing this arrangement, depends on the general law indicated.  As immediately after looking at the sun we cannot perceive the light of a fire, while by looking at the fire first and the sun afterwards we can perceive both; so, after receiving a brilliant, or weighty, or terrible thought, we cannot appreciate a less brilliant, less weighty, or less terrible one, while, by reversing the order, we can appreciate each.  In Antithesis, again, we may recognize the same general truth.  The opposition of two thoughts that are the reverse of each other in some prominent trait, insures an impressive effect; and does this by giving a momentary relaxation to the faculties addressed.  If, after a series of images of an ordinary character, appealing in a moderate degree to the sentiment of reverence, or approbation, or beauty, the mind has presented to it a very insignificant, a very unworthy, or a very ugly image; the faculty of reverence, or approbation, or beauty, as the case may be, having for the time nothing to do, tends to resume its full power; and will immediately afterwards appreciate a vast, admirable, or beautiful image better than it would otherwise do.  Conversely, where the idea of absurdity due to extreme insignificance is to be produced, it maybe greatly intensified by placing it after something highly impressive:  especially if the form of phrase implies that something still more impressive is coming.  A good illustration of the effect gained by thus presenting a petty idea to a consciousness that has not yet recovered from the shock of an exciting one, occurs in a sketch by Balzac.  His hero writes to a mistress who has cooled towards him the following letter: 

“Madame, Votre conduite m’etonne autant qu’elle m’afflige Non contente de me dechirer le coeur par vos dedains vous avez l’indelicatesse de me retenir une brosse a dents, que mes moyens ne me permettent pas de remplacer, mes proprietes etant grevees d’hypotheques

“Adieu, trop, belle et trop ingrate ainie!  Puissions nous nous revoir dans un monde meilleur!

“Charles Edouard”

63.  Thus we see that the phenomena of Climax, Antithesis, and Anticlimax, alike result from this general principle.  Improbable as these momentary variations in susceptibility may seem, we cannot doubt their occurrence when we contemplate the analogous variations in the susceptibility of the senses.  Referring once more to phenomena of vision, every one knows that a patch of black on a white ground looks blacker, and a patch of white on a black ground looks whiter, than elsewhere.  As the blackness and the whiteness must really be the same, the only assignable cause for this is a difference in their actions upon us, dependent upon the different states of our faculties.  It is simply a visual antithesis.
