Which one of these four quotes is attributed to Pierre Beaumarchais?
→ Even if I knew that tomorrow the world would go to pieces, I would still plant my apple tree.
→ Like dogs in a wheel, birds in a cage, or squirrels in a chain, ambitious men still climb and climb, with great labor, and incessant anxiety, but never reach the top.
→ Never seem more learned than the people you are with. Wear your learning like a pocket watch and keep it hidden. Do not pull it out to count the hours, but give the time when you are asked.
→ It is not necessary to understand things in order to argue about them.
