What about you being the highest authority in your own life?
Then people like you call me 'delusional', 'selfish', 'illogical' and such.
When someone strives to be the highest authority in one's own life, many other people don't view this favorably and will try to get the person to conform. Obviously, these many other people have expectations about how people should behave. This has practical consequences, such as mobbing in the workplace, racial, sexual etc. related discrimination.
Many people will say one should be the highest authority in one's own life, but few will peacefully allow others to be that.
Both schemes expect me to adopt a set of views where I will play only a minor role in my own life.
I don't see this at all. Not even a little.
For example, if I am unhappy and want to be happy, and turn to science for some help, what happens? In the best case, they refer me to neuroscience, suggesting I wait until they have some conclusive findings on what makes people happy. By the time they get them, I'll probably be dead. And even if they do have some conclusions, they are statistical averages, and the things they do suggest are what folk wisdom and common sense have been saying for centuries anyway.
The things that are most important in my life -my happiness, my suffering, my meaning of life- have to be put on the side-burner if I am to adopt a science-centred view of life.
And also, are you happy to think of yourself as a 'mass of living matter', for example? Or do you think that scientific findings are not obligatory? If they are not obligatory, then do the benefits of scientific research outweigh its costs and pollution?
Science has 'proven theism wrong'. How reliable is that proof? How much did that cost? How much pollution was created in the course of it? Was it worth it?
