Which one of these four quotes is attributed to Charles Darwin?
→ The highest possible stage in moral culture is when we recognize that we ought to control our thoughts.
→ Few people know how to take a walk. The qualifications are endurance, plain clothes, old shoes, an eye for nature, good humor, vast curiosity, good speech, good silence and nothing too much.
→ We are not the same persons this year as last; nor are those we love. It is a happy chance if we, changing, continue to love a changed person.
→ Nothing strengthens the judgment and quickens the conscience like individual responsibility.
