@Olivier5,
I once mentioned that I wanted to talk about materialism, and never got around to it since I'd have to gather and write up my thoughts on it.
I have my own use of the word, which has nothing to do with the matter of people being materialistic, that quite derogatory word, a word also oft having to do with philosophy.
I don't consider myself spiritual in the way most people mean. For example, I've a friend who thinks of the mountains as spiritual places. I'm happy thinking of them as mountains, with all their attributes. I observe that the beliefs of native americans are spiritual in their understandings of the sun and moon and earth. Mine are not, mine are that they are material.
In the common sense of the word, I do like finely wrought things, though I don't have to have them as my own - ceramics, paintings, espresso makers, nice linens. I also like old ratty things, that others would throw out, from my old blue jeans, to a cracked cup that still holds fluid.
But more in my sense of material, I like the beauty of the environment: the nature of nature, in all its glory, even its violence, the way things work together, like the human body does with its Krebs Cycle, and how systems work, with a kind of coherence. I like the nature of the petroglyphs behind the highway near my housing area, I like the roadrunner bird romping through a sandy yard on my own street, the quails traipsing between the trees. together.
I consider spirituality as such as other people's woo woo, and my view of the word materialism as a search for beauty. Beauty, as a kind of fit. By saying other people's woo woo, I don't mean that as mocking, just that I'm not interested in what I take as projections.
I am interested in matters of the mind and heart, but I don't consider that spirituality. I consider it living.
A tangent, yes, but a riposte to your (and most people's) use of the word materialism.
