Heard melodies are sweet, but those unheard Are sweeter; therefore, ye soft pipes, play on; Not to the sensual ear, but, more endear'd, Pipe to the spirit ditties of no tone.

O magic sleep! O comfortable bird, That broodest o'er the troubled sea of the mind Till it is hush'd and smooth!

I have loved the principle of beauty in all things.

I am sailing with thee through the dizzy sky! How beautiful thou art!

Through the dancing poppies stole A breeze, most softly lulling to my soul.

The excellency of every art is its intensity, capable of making all disagreeable evaporate.

I find that I can have no enjoyment in the world but the continual drinking of knowledge. I find there is no worthy pursuit but the idea of doing some good for the world.
