Ralph Waldo Emerson: Each and All.

Not from his fellows only man may learn

Rights to compare and duties to discern;

All creatures and all objects, in degree,

Are friends and patrons of humanity.

There are to whom the garden, grove, and field

Perpetual lessons of forbearance yield;

Who would not lightly violate the grace

The lowliest flower possesses in its place;

Nor shorten the sweet life, too fugitive,
