Our chief usefulness to humanity rests on our combining power with high purpose. Power undirected by high purpose spells calamity, and high purpose by itself is utterly useless if the power to put it into effect is lacking.
Brave, bold men, these are what we want. What we want is vigour in the blood, strength in the nerves, iron muscles and nerves of steel, not softening namby-pamby ideas.
Thought is like a bubble rising to the surface. When thought is joined to will, we call it power. That which strikes the sick person whom you are trying to help is not thought, but power.
