"I hold an actual knowledge very cheap. Hear the rats in the wall,
see the lizard on the fence, the fungus under foot, the lichen on
the log. What do I know sympathetically, morally, of either of these
worlds of life?--How many times we must say Rome and Paris, and

We cannot help smiling, perhaps laughing, at the odd mixture of Rome

We have become familiar with his doctrine of "Self-Reliance," which is
the subject of the second lecture of the series. We know that he
always and everywhere recognized that the divine voice which speaks
authoritatively in the soul of man is the source of all our wisdom.
It is a man's true self, so that it follows that absolute, supreme
