“A wise man once said that all human activity is a form of play. And the highest form of play is the search for Truth, Beauty and Love. What more is needed? Should there be a ‘meaning’ as well, that will be a bonus? If we waste time looking for life’s meaning, we may have no time to live — or to play.”

“The creation of wealth is certainly not to be despised, but in the long run the only human activities really worthwhile are the search for knowledge, and the creation of beauty. This is beyond argument, the only point of debate is which comes first.”

“As Solomon himself had remarked, 'We can be sure of talent, we can only pray for genius.' But it was a reasonable hope that in such concentrated society some interesting reactions would take place. Few artists thrive in solitude and nothing is more stimulating than the conflict of minds with similar interests. So far, the conflict had produced worthwhile results in sculpture, music, literary criticism and film making. It was still too early to see if the group working on historical research would fulfil the hopes of its instigators, who were frankly hoping to restore mankind's pride in its own achievements. Painting still languished which supported the views of those who considered that static, two dimensional forms of art had no further possibilities. It was noticeable, though a satisfactory explanation for this had not yet been produced that time played an essential part in the colony's achievements.”

“No utopia can ever give satisfaction to everyone, all the time. As their material conditions improve, men raise their sights and become discontented with power and possessions that once would have seemed beyond their wildest dreams. And even when the external world has granted all it can, there still remain the searchings of the mind and the longings of the heart.”

“There's no real objection to escapism, in the right places... We all want to escape occasionally. But science fiction is often very far from escapism, in fact you might say that science fiction is escape into reality... It's a fiction which does concern itself with real issues: the origin of man; our future. In fact I can't think of any form of literature which is more concerned with real issues, reality.”

“What is human memory?" Manning asked. He gazed at the air as he spoke, as if lecturing an invisible audience - as perhaps he was. "It certainly is not a passive recording mechanism, like a digital disc or a tape. It is more like a story-telling machine. Sensory information is broken down into shards of perception, which are broken down again to be stored as memory fragments. And at night, as the body rests, these fragments are brought out from storage, reassembled and replayed. Each run-through etches them deeper into the brain's neural structure. And each time a memory is rehearsed or recalled it is elaborated. We may add a little, lose a little, tinker with the logic, fill in sections that have faded, perhaps even conflate disparate events. "In extreme cases, we refer to this as confabulation. The brain creates and recreates the past, producing, in the end, a version of events that may bear little resemblance to what actually occurred. To first order, I believe it's true to say that everything I remember is false.”

“Perhaps it is better to be un-sane and happy, than sane and un-happy. But it is the best of all to be sane and happy. Whether our descendants can achieve that goal will be the greatest challenge of the future. Indeed, it may well decide whether we have any future.”
