"It is an experience we are continually encountering in other walks of life," continues Dr. Carpenter, "that particular persons are guided--some apparently by an original and others by _an acquired intuition_--to conclusions for which they can give no adequate reason, but which subsequent events prove to have been correct." And this, I take it, implies what I have been above insisting on, namely, that on becoming intense, knowledge seems also to become unaware of the grounds on which it rests, or that it has or requires grounds at all, or indeed even exists. The only issue between myself and Dr. Carpenter would appear to be that Dr. Carpenter, himself an acknowledged leader in the scientific world, restricts the term "scientific" to the people who know that they know, but are beaten by those who are not so conscious of their own knowledge; while I say that the term "scientific" should be applied (only that they would not like it) to the nice sensible people who know what's what rather than to the professorial classes. And this is easily understood when we remember that the pioneer cannot hope to acquire any of the new sciences in a single lifetime so perfectly as to become unaware of his own knowledge. As a general rule, we observe him to be still in a state of active consciousness concerning whatever particular science he is extending, and as long as he is in this state he cannot know utterly. It is, as I have already so often insisted, those who do not know that they know so much who have the firmest grip of their knowledge: the best class, for example, of our English youth, who live much in the open air, and, as Lord Beaconsfield finely said, never read. These are the people who know best those things which are best worth knowing--that is to say, they are the most truly scientific.
