"It is just as ridiculous to get excited & hysterical over a coming cultural change as to get excited & hysterical over one's physical aging . . . There is legitimate pathos about both processes; but blame & rebellion are essentially cheap, because inappropriate, emotions . . . It is wholly appropriate to feel a deep sadness at the coming of unknown things & the departure of those around which all our symbolic associations are entwined. All life is fundamentally & inextricably sad, with the perpetual snatching away of all the chance combinations of image & vista & mood that we become attached to, & the perpetual encroachment of the shadow of decay upon illusions of expansion & liberation which buoyed us up & spurred us on in youth. That is why I consider all jauntiness, & many forms of carelessly generalised humour, as essentially cheap & mocking, & occasionally ghastly & corpselike. Jauntiness & non-ironic humour in this world of basic & inescapable sadness are like the hysterical dances that a madman might execute on the grave of all his hopes. But if, at one extreme, intellectual poses of spurious happiness be cheap & disgusting; so at the other extreme are all gestures & fist-clenchings of rebellion equally silly & inappropriate—if not quite so overtly repulsive. All these things are ridiculous & contemptible because they are not legitimately applicable . . . The sole sensible way to face the cosmos & its essential sadness (an adumbration of true tragedy which no destruction of values can touch) is with manly resignation—eyes open to the real facts of perpetual frustration, & mind & sense alert to catch what little pleasure there is to be caught during one's brief instant of existence. Once we know, as a matter of course, how nature inescapably sets our freedom-adventure-expansion desires, & our symbol-&-experience-affections, definitely beyond all zones of possible fulfilment, we are in a sense fortified in advance, & able to endure the ordeal of consciousness with considerable equanimity . . . Life, if well filled with distracting images & activities favourable to the ego's sense of expansion, freedom, & adventurous expectancy, can be very far from gloomy—& the best way to achieve this condition is to get rid of the unnatural conceptions which make conscious evils out of impersonal and inevitable limitations . . . get rid of these, & of those false & unattainable standards which breed misery & mockery through their beckoning emptiness."
