A Quote by Zimmermann on ambition, egotism, good, imagination, indolence, luxury, nature, pride, principles, and rest

If you ask me which is the real hereditary sin of human nature, do you imagine I shall answer pride, or luxury, or ambition, or egotism? No; I shall say indolence. Who conquers indolence will conquer all the rest. Indeed all good principles must stagnate without mental activity.
