This, if we like to use the word, is Shakespeare’s ‘pessimism’ in King Lear.  As we have seen, it is not by any means the whole spirit of the tragedy, which presents the world as a place where heavenly good grows side by side with evil, where extreme evil cannot long endure, and where all that survives the storm is good, if not great.  But still this strain of thought, to which the world appears as the kingdom of evil and therefore worthless, is in the tragedy, and may well be the record of many hours of exasperated feeling and troubled brooding.  Pursued further and allowed to dominate, it would destroy the tragedy; for it is necessary to tragedy that we should feel that suffering and death do matter greatly, and that happiness and life are not to be renounced as worthless.  Pursued further, again, it leads to the idea that the world, in that obvious appearance of it which tragedy cannot dissolve without dissolving itself, is illusive.  And its tendency towards this idea is traceable in King Lear, in the shape of the notion that this ’great world’ is transitory, or ‘will wear out to nought’ like the little world called ‘man’ (IV. vi. 137), or that humanity will destroy itself.[191] In later days, in the drama that was probably Shakespeare’s last complete work, the Tempest, this notion of the transitoriness of things appears, side by side with the simpler feeling that man’s life is an illusion or dream, in some of the most famous lines he ever wrote: 

     Our revels now are ended.  These our actors,
     As I foretold you, were all spirits and
     Are melted into air, into thin air: 
     And, like the baseless fabric of this vision,
     The cloud-capp’d towers, the gorgeous palaces,
     The solemn temples, the great globe itself,
     Yea, all which it inherit, shall dissolve
     And, like this insubstantial pageant faded,
     Leave not a rack behind.  We are such stuff
     As dreams are made on, and our little life
     Is rounded with a sleep.

These lines, detached from their context, are familiar to everyone; but, in the Tempest, they are dramatic as well as poetical.  The sudden emergence of the thought expressed in them has a specific and most significant cause; and as I have not seen it remarked I will point it out.

Prospero, by means of his spirits, has been exhibiting to Ferdinand and Miranda a masque in which goddesses appear, and which is so majestic and harmonious that to the young man, standing beside such a father and such a wife, the place seems Paradise,—­as perhaps the world once seemed to Shakespeare.  Then, at the bidding of Iris, there begins a dance of Nymphs with Reapers, sunburnt, weary of their August labour, but now in their holiday garb.  But, as this is nearing its end, Prospero ’starts suddenly, and speaks’; and the visions vanish.  And what he ‘speaks’ is shown in these lines, which introduce the famous passage just quoted:
