““Suppose that one and the same reality exhibits one aspect when it stands in relation to another object; two aspects when it stands in relation in two different objects; three aspects when it stands in relation to three different objects. The reality of one aspect never proves the unreality of another aspect, for all these three aspects can be equally real. A tree appears to us as a vegetable; it appears to some birds as a shelter; and it appears to some worms as a food. The reality of its aspect as a vegetable never proves the unreality of its aspect as food, nor the reality of its aspect as food disproves the reality of its aspect as shelter. The real tree does not exist beyond or behind the vegetable. We can rely upon its reality, and make use of it to a fruitful result. At the same time, the birds can rely on its reality as a shelter, and build their nests in it; the worms, too, can rely on its reality as food, and eat it-to their satisfaction.””
