"You know, we can compare our training, our power of reason, to a blind person using a guide dog. Now an untrained dog would be very helpful to a blind person. It would bark when others were around, for example. However a dog trained in specific skills is amazingly helpful. The dog knows when to stop at curbs, walk around obstacles that the person right (sic) run their head into. A guide dog is also taught a skill called 'intelligent disobedience', and even if the blind person encourages the dog forward it won't obey, but it will pull the person back from danger.
Now, it can take a year or more of training for the dog to learn the amazing skills that are so helpful to a blind person. Likewise, our raw, untrained power of reason can help us to a degree. However, it can be amazing if we take the time to train it."
