What are plants doing? What are plants all about? They serve human beings by being decorative, but what is it from its own point of view? It's using up air; it's using up energy. It's really not doing anything except being ornamental. And yet here's this whole vegetable world, cactus plants, trees, roses, tulips, and edible vegetables, like cabbages, celery, lettuce - they're all doing this dance.
The most refined abstractions of logic conduct to a view of life, which, though startling to the apprehension, is, in fact, that which the habitual sense of its repeated combinations has extinguished in us. It strips, as it were, the painted curtain from this scene of things.

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.
