Teaching (n.) philosophy today means feeding the pupil foods not to suit his taste but to change it.
Teaching (n.) depends on the pupil responding in a particular way: the encouragements that train a dog to retrieve are out of the question with a cat.
Teaching (n.) a child to go on is not an indirect way of signalling meanings to a mind that already has a private language — as if the child silently asked, "Does he want me to continue?"
Teaching (n.) seen as drill is like wiring a switch to a bulb, and forgetting a word's meaning is the connexion breaking down.
Teaching (n.) taken as the cause of understanding is only a hypothesis, and it is conceivable that understanding and obeying should have happened without the person ever having been taught the language.

Teaching (n.) a game one cannot learn is impossible, so the colour-blind cannot demonstrate normal use of colour words.
