THERE is no doubt that many people are susceptible to the repetition of a single message. No matter how stupid the message, if enough people say it often enough, a large percentage of those who hear it will begin to believe it. That’s the basis of advertising and also propaganda: it’s how you make ideas fashionable, even scientific ideas. But just because an idea is fashionable doesn’t make it right and just because an idea is right, well it doesn’t mean it represents the truth.
Fashion is in fact the lowest form of ideology and I have little regard for fashionable ideas – even fashionable scientific ideas. I also have little regard for what many claim to be good and wholesome ideas. My interest is in the facts, the evidence – the truth particularly as it pertains to the natural world.
There is intrinsic good in having a deep understanding, based on truths, of aspects of the natural world. For example, it is through understanding electricity – what it is and how it can be generated – that it many of our basic physical needs are now met at the flick of a switch: the lights come on, the house warms up, the kettle boils water. But not everyone studies science to discover useful things, for some it is the chase after facts and the thrill that comes with their discovery, for others an interest in an aspect of the puzzle that is the natural world in the hope of finding order in the universe.
But to be successful at science there is a need for a particular type of discipline – a discipline that is not necessary in many other intellectual pursuits. There is a need to be honest to reality and to always test theory against reality. In this respect science is different from the modern arts.
But science has not always been so different from art. For example, Leonardo da Vinci studied anatomy to become a better artist. That was during a period in Europe when the artist’s goal was assumed to be the representation of reality – of nature. But then a time came when European artists renounced representation as their goal. Art now is about emotion, culture and fashion – few modern day artists attempt to depict the world as it really is. This may or may not be a good thing for art but it clearly makes art something very different from science.
Science is meant to be about reality – it is meant to be about discovery and understanding and truth. Science is not meant to be about emotion or culture or even fashion. But how can you tell whether a conversation about a scientific issue is based on truth or fashion?
