Past ideas of connectedness between people and the importance of responsibility have been replaced by ideas of the freedom and rights of the individual. The core value of religion is spirituality. If we are possessed of spiritual souls, and I believe we are, we can never form successful and happy societies if we ignore the spiritual dimension. By spirituality I mean the sum of those things that our nature thirsts for in order to lead a fulfilled life. In summary, we need to grow in wisdom and in love.
Wisdom means understanding and working the principles that underpin decent human relations.
And, in practical terms, love means treating your neighbour with the same courtesy and respect that you would wish to receive yourself. It seems our nature is such that we will only ever be persuaded to act in this manner in large numbers if we do so for the love of a Supreme Being. Let me end on a lighter note. There was a very long discussion in a Jewish theological seminary about proofs of the existence of God. Things became very confused.
