The Value of Thinking II

You see, it is so difficult to struggle with human abstractness in this field; because once you have grasped this flexibility of thought, you will also understand that a flexible thought cannot occur in any old way, here or there. You cannot, for example, find a land animal in the water; you cannot accustom a bird, which is suited to the air, to live deep down in the water. If you go to the living, you cannot do otherwise than to accept the idea that one must not take it out of its element. You have to keep that in mind.
