"Love Is Wise, Hatred Is Foolish."
The moral legacy that the philosopher Bertrand Russell leaves to the human race in a 1959 documentary is this: "Love is wise, hatred is foolish." He elaborates that the world "is getting more and more interconnected. We have to learn to put up with the fact that some people say things that we don't like...which is absolutely vital to the continuation of human life on this planet." Is his moral legacy good, and correlatively, right?
Morality is about identifying and recognizing behavioural societal standards and norms, and discharging humans' societal duty and responsibility so that we all can live a good life. Humans are sensuous and rational beings capable of freely determining the moral action to take in achieving their goals and playing their roles. Despite cultural differences, certain actions are commonly believed and practised as having intrinsic value in themselves, irrespective of their consequences.
We can reason from the general interconnected coherent beliefs to freely determine what we should do in special circumstances. If we accept survival is our basic common goal in life, achieving the beneficial consequence by loving each other is good, and correlatively, wise for the human race. It should be easy to agree that the consequence of interconnected humans united in natural harmony cannot be bad or foolish.
If we accept the fact that we have to live together peacefully and life is good, it implies that discharging our inherent duties by complying with the necessary societal obligations (eg tolerance of differences) is probably right, and upon reflection, self-evidently true, as the best option for the well-being of human society. I say "probably" because excessive assertion of being (exclusively) right can generate unnecessary emotions like hatred from others who could not accept and recognize it. For those who desire a realistic rule-based human society to thrive, it is justifiable that they ought to continue to live by their moral responsibility and identity to love and not to hate!
