I think I can agree with all of those tenets of Humanism. Sign me up!
I don't find anything particularly egocentric about those beliefs. They certainly did not say that the freedom of the individual human is the highest value. I think there was an acknowledgement of the interconnectedness of humans with other species and the planet and that are futures are intertwined.
Randy: that was an interesting article on science. I agree, the bias of the researcher can never be fully removed from that which is researched, that is why scientific methods must have methods of measurement that are falsifiable and repeatable and why they are subject to peer review. While humans may never be able to achieve 100% detachment in their rational and reasoning, I don't think scientist claim that they do, or that they are without ego. However, the scientific method of analysis is an attempt to remove bias, and draw rational conclusions about our world through measurable evidence. Just because it cannot guarantee to accomplish this 100%, is no reason to abandon the method and go backwards, basing our decisions on anecdotal evidence and superstition.
The scientific method is still superior to what preceded it and until a better method of drawing conclusions comes along, it makes sense to use it and try to improve upon it.
