Rudolf Steiner: "By what right do you declare the world finished without thinking? Does not the world bring forth thinking in human heads with the same necessity as it brings forth blossoms on the plant? Plant a seed in the earth. It puts forth roots and stem. It unfolds into leaves and blossoms. Set the plant before you. It links itself to a specific concept in your soul. Why does this concept belong to the plant any less than the leaves and blossoms do? You might reply that the leaves and blossoms are present without a perceiving subject, while the concept appears only when a human being confronts the plant. Very well. But blossoms and leaves arise in the plant only when there is earth in which the seed can be laid and light and air in which leaves and blossoms can unfold. Just so, the concept of the plant arises when thinking consciousness approaches the plant."
