When you go by the assumption that all people need to be happy then morality flies out the window. Everyone being happy would include harmful behavior. Why someone should be happy is because people want to be however understanding what happiness is would be more important. Whether someones happiness is eating chocolate covered strawberries all day or having sex with a multitude of people all day doesn't really get into whether that might actually be harmful or not. We know the chemicals needed in our brain for happiness so it would be no different if we just pumped the proper doses into the brain then it wouldnt matter at that point what was happening in our environment.My inspiration for starting this thread is from another regarding where atheists and other secularists get their morality from. For the record, I have stopped calling myself a Secular Humanist because I'm not satisfied with secular ethics.
The problem is that I see no purpose or meaning to life from a secular viewpoint. If we are just the sum of our cells, then what's the purpose to life? There is no objective purpose or meaning as far as I can tell. Some might say that the purpose is to be happy. But if I was asked questions like 1.) why bother to be happy? and 2.) what difference would it make if I was happy or not?, I wouldn't know what to say.
I like the thought of being happy. I want to be happy. I imagine most people do. But as for why I should want to be happy or why I ought to be happy, I have no idea. If someone asked me, I would be completely lost for words. I really have no clue. If life is ultimately meaningless and exists for no purpose, why attach meaning or purpose where it previously didn't exist? What's the point? What difference does it make? Why bother? Is it because it makes for a harmonious and peaceful society? If so, then the question I would ask is: why care about harmony and peace? If some folks reply because they're better than other alternatives, the question becomes: why care about which alternatives are better than other alternatives?
In the end, I find Secular Humanism not much better than the Evangelical Christian fundamentalism I cheerfully renounced nine years ago!
For Secular Humanists, where do you think I'm going wrong?
One of the more important things to consider would be 'true' happiness. Sure there are lots of things that can make us happy but true happiness for any individual would be achieved with a healthy mind and body and science can tell us with great precision what that might entail. We know that some people might like to be harmed gaining the endorphins for happiness but science can tell us there would surely be less harmful ways of getting these endorphins and adrenaline spikes.
