We are always making assumptions, without knowing that we are doing so, and arguing from them. And this fact is responsible for half the error and half the misunderstanding of each other which ever takes place. It is the work of Philosophy to produce the attitude of mind which makes us detect these assumptions, drag them out into the light of day, and put them on their trial. And it is as doing this that some admixture of Philosophy in any system of education must seem to those who accept this view of it, not only valuable but essential to right thinking and the understanding of the world and of each other.
