And the adjective "cosmic" means, of course, "related to the whole universe." Ordinary emotion may be more than individual in its relations.

I mean that your feelings may be moved by the thought or the perception of something relating not only to your own life but also to the lives of many others.
The largest form of such ordinary emotion is what would be called national feeling, the feeling of your own relation to the whole nation or the whole race.

But there is higher emotion even than that.

When you think of yourself emotionally not only in relation to your own country, your own nation, but in relation to all humanity, then you have a cosmic emotion of the third or second order.

I say "third or second," because whether the emotion be second or third rate depends very much upon your conception of humanity as One.
