Teaching students the evidence for and against Darwinism is not the same as teaching intelligent design. The U.S. Congress has officially endorsed teaching students 'the full range of scientific views' about Darwinian evolution.
All the various types of teachings and spiritual paths are related to the different capacities of understanding that different individuals have. There does not exist, from an absolute point of view, any teaching which is more perfect or effective than another. A teaching's value lies solely in the inner awakening which an individual can arrive at through it. If a person benefits from a given teaching, for that person that teaching is the supreme path, because it is suited to his or her nature and capacities. There's no sense in trying to judge it as more or less elevated in relation to other paths to realization.
Active critical reflection is necessary in every aspect of our teaching, not only in front of a class. We must try to reevaluate our own values and experiences as they relate to our teaching. Our assumptions and theories about teaching composition must remain open to inspection, evaluation, and revision, a condition that requires an active inquiry paralleling the inquiry in which we engage our students.
Jane says she will devote her whole life to teaching, and never, never marry, because you are paid a salary for teaching, but a husband won't pay you anything, and growls if you ask for a share in the egg and butter money.
