As a species we are a predominantly intelligent and exploratory animal, and beliefs harnessed to this fact will be the most beneficial for us. A belief in the validity of the acquisition of knowledge and a scientific understanding of the world we live in, the creation and appreciation of aesthetic phenomena in all their many forms, and the broadening and deepening of our range of experiences in day-to-day living, is rapidly becoming the 'religion' of our time. Experience and understanding are our rather abstract god-figures, and ignorance and stupidity will make them angry. Our schools and universities are our religious training centres, our libraries, museums, art galleries, theatres, concert halls and sports arenas are our places of communal worship. At home we worship with our books. newspapers. magazines, radios and television sets. In a sense, we still believe in an after-life, because part of the reward obtained from our creative works is the feeling that, through them, we will 'live on' after we are dead. Like all religions, this one has its dangers, but if we have to have one, and it seems that we do, then it certainly appears to be the one most suitable for the unique biological qualities of our species. Its adoption by an ever-growing majority of the world population can serve as a compensating and reassuring source of optimism to set against the pessimism (...) concerning our immediate future as a surviving species.
