 Plants do not learn from experience. They do not acquire beliefs and change them in light of things that happen to them. Nor do they have any desires. To be sure, we sometimes speak as if they do. We say that the wilting daffodils are just begging to be watered. But we recognize full well that this is a harmless façon de parler. What we mean is that the daffodils need water. There is here no goal-directed behavior, no purpose, nothing that is the result of any learning, no desire for water.
