Nature knows no pause in progress and development, and attaches her curse on all inaction.

One must ask children and birds how cherries and strawberries taste.

In nature we never see anything isolated, but everything in connection with something else which is before it, beside it, under it and over it.

He is happiest, be he king or peasant, who finds peace in his home.

On all the peaks lies peace.

Piety is not a goal but a means to attain through the purest peace of mind the highest culture.

Personality is everything in art and poetry.

Science arose from poetry... when times change the two can meet again on a higher level as friends.

Superstition is the poetry of life.

Dream no small dreams for they have no power to move the hearts of men.
