Reconcile those who are at strife, prevent lawsuits; incline children to duty, fathers to kindness; promote happy marriages; prevent annoyances; free… - Jean-Jacques Rousseau

Society must be studied in the individual and the individual in society; those who desire to treat politics and morals apart from one another will never understand either

Todo hombre nacido en la esclavitud, nace para la esclavitud; nada

Everything fluctuates on earth; nothing remains in a constant and lasting form, and those affections which are attached to external things necessarily change with their object. We are ever looking forward or backward, ruminating on what is past, and can return no more, or anticipating the future, which may never arrive; there is nothing solid to which the heart can attach, itself, neither have we here below any pleasures that are lasting. Permanent, happiness is, I fear, unknown, and scarcely is there an instant in our most lively enjoyments when the heart can truly say, May this moment last forever!!! How then can such a fugitive state be called happiness, which leaves an uneasy void in the heart, which ever prompts us to regret something that is past, or desire something for the future?
