in order of value, and logical evolution, that is most suiting, to the most productive and efficient method of learning and using all 3
a life with none of these is void of life at all, and life by any less than all, can hardly be considered a life at all. I think of it as 1d, 2d, 3d....which one do you want to live in, and which one do you think has the most opportunities? (sort of a suggestive, rhetorical question, sorry)
philosophy- I lump this in with reason and critical thinking then followed by...
science-since we can now reason, we may now interpret our data using our skills and reason, for science
religion-an intuition in to the unknown and unexplainable, lastly but most importantly an optimism to keep us trying even though things may look bleak
I think that is the basic/necessary 3, generally. too add to the list, I cant think of any others to add that wouldn't encroach on another's territory
in some form of the other, I think this triad must exist, the smallest shape is a triangle.
one could argue we don't need religion, but then without it, that eliminates styles and cultures almost, of people. and that diversity of ideas and influences is both our curse, and our blessing
no we don't need to speculate about the unknown (((religion and I'm not saying that's all there is to it, it does so much more for us.))) but that would be akin to a life without fun, and there is most certainly a need for that, to create a real desire to live. now if you find fun in philosophy or science, then great, but there are so many unknowns in both, that like I said, its a necessity.
