Si el destino de un hombre depende de la desgracia de otro, entonces no existe buena fortuna para nadie.

Nothing is part of everything.

Lleve cada uno su culpa y no habrá culpables.

Bajo la competencia perfecta, en el largo plazo, ninguna compañía percibe beneficio económico.

There has never lived a people worth writing about who have not shaped out a destiny for themselves, or carved out their own opportunity.

Pártase de cualquier punto. Todos son iguales. Todos llevan a un punto de partida.

There is no such thing as destiny. We ourselves shape our lives.

Cada uno es hijo de sus obras.

Men do not shape destiny. Destiny produces the man for the hour.

There are no uninteresting fates, and each man takes away the universe when he dies.

Nature having given no property to anyone.

There is no wealth but life.

It is only just that anything that grows up on its own should feel it has nothing to repay for an upbringing which it owes no one.

It is a universal law – have no illusions – that every creature alive is attached to nothing so much as to its own self-interest.
