How wonderful the work of nature! How benevolent its design!
Look deep into nature, and then you will understand everything better.
If you want to achieve greatness stop asking for permission.
Study nature, love nature, stay close to nature. It will never fail you.
The butterfly counts not months but moments, and has time enough.
The love for all living creatures is the most noble attribute of man.
Man is still the greatest miracle and the greatest problem on this earth.
In every walk with nature one receives far more than he seeks.
