I suppose wisdom could be considered an antonym of delusion. In Macbeth, the title couple are infected by the latter to such a degree that the normal courses of life, its processes and stages, are taken away from them by their lack of the former. There is a telling moment early in the play (1.7) where Macbeth, in considering the nature of his ambition, recognizes that a goal can become so all-consuming that "here, upon this bank and shoal of time,/ We'ld jump the life to come." But it doesn't prevent what follows, and late in the play (5.5) after a series of atrocities and disasters, and the death by suicide of his queen, he speaks the famous lines (which I've come to understand better with time) wherein he describes a world without process and meaningful work towards goals - where time equals emptiness, and actions are futile:

To-morrow, and to-morrow, and to-morrow,

Creeps in this petty pace from day to day

To the last syllable of recorded time,

And all our yesterdays have lighted fools

The way to dusty death. Out, out, brief candle!

Life's but a walking shadow, a poor player

That struts and frets his hour upon the stage

And then is heard no more: it is a tale

Told by an idiot, full of sound and fury,

Signifying nothing.

Of course, the subtext (sometimes called the underthought) is simultaneously telling us something quite different, that life doesn't have to be this way, and that wisdom can prevent the errors in judgement that would lead to an end such as this one. Now where could wisdom like that be learned?
