Quote

It is no little wisdom for you to keep yourself in silence and in good peace when evil words are spoken to you, and to turn your heart to God and not to be troubled with the judgment of others

There is a road from the eye to heart that does not go through the intellect.

A scientific man ought to have no wishes, no affections, - a mere heart of stone

Since my earliest childhood a barb of sorrow has lodged in my heart. As long as it stays I am ironic, if it is pulled out I shall die

I am certain of nothing but the holiness of the heart's affections, and the truth of imagination.

You must have the bird in your heart before you can find it in the bush.
