Ultimately, I believe the very existence of a single equation that can describe the entire universe in an orderly, harmonious fashion implies a design of some sort. However, I do not believe that this design gives personal meaning to humanity. No matter how dazzling or elegant the final formulation of physics may be, it will not uplift the spirits of billions and give them emotional fulfilment. No magic formula coming from cosmology physics will enthral the masses and enrich their spiritual lives.
For me, the real meaning in life is that we create our own meaning. It is our destiny to carve out our own future, rather than have it handed down from some higher authority. Einstein once confessed that he was powerless to give comfort to the hundreds of well-meaning individuals who wrote stacks of letters pleading with him to reveal the meaning of life. As Alan Guth has said, “It’s ok to ask those questions, but one should not expect to get a wiser answer from a physicist. My own emotional feeling is that life has a purpose — ultimately, I’d guess that the purpose it has is the purpose that we’ve given it and not a purpose that came out of any cosmic design.”
I believe that Sigmund Freud, with all his speculations about the dark side of the unconscious mind, came closest to the truth when he said that what gives stability and meaning to our minds is work and love. Work helps to give us a sense of responsibility and purpose, a concrete focus to our labours and dreams. Work not only gives discipline and structure to our lives, it also provides us with a sense of pride, accomplishment, and a framework for fulfilment. And love is an essential ingredient that puts us within the fabric of society. Without love, we are lost, empty without roots. We become drifters in our own land, unattached to the concerns of others.
Beyond work and love, I would add two other ingredients that give meaning to life. First, to fulfil whatever talents we are born with. However blessed we are by fate with different abilities and strengths; we should try to develop them to the fullest, rather than allow them to atrophy and decay. We all know individuals who did not fulfil the promise they showed in childhood. Many of them became haunted by the image of what they might have become. Instead of blaming fate, I think we should accept ourselves as we are and try to fulfil whatever dreams are within our capability.
Second, we should try to leave the world a better place than when we entered it. As individuals, we can make a difference, whether it is to probe the secrets of Nature, to clean up the environment and work for peace and social justice, or to nurture the inquisitive, vibrant spirit of the young by being a mentor and a guide.
My blunt is done, which means I should get back to work. Later.
