Even outside this understanding of meaning, too much thought can easily lead to -- more thought, no concreteness with which to make philosophy even useful to one's life outside of meaning; one philosophizes for its own sake, all abstractions lead to other abstractions, and the concept of progress, intertwined as it is with the real world, becomes held in a sort of contempt -- the real world is no longer what it once was held to be;
True. However, I believe this is why we invented science: to be that stabilizing element, the "reality check" upon philosophy pertaining to the nature of reality.
Secondly, I think that as the relevance of science begins to dwindle as Modernism fades, what you say becomes even more poignant. People are beginning to put more stock into ideas and cultures rather than real consequences. This is why I appreciate the humor of Kierkegaard who understood the silly nature of flavoring reality through ideas rather than confronting reality itself.
"What the philosophers say about Reality is often as disappointing as a sign you see in a shop window which reads: Pressing Done Here. If you brought your clothes to be pressed, you would be fooled; for only the sign is for sale." - Soren Kierkegaard, from Either/Or
And yet, at least philosophy gives me a good way to make friends with whom I relate well. If philosophy is found to be self-perpetuating and ultimately impractical in itself, I might as well
make it practical by using it as a device for social gain (though I can't say I've had much luck *sigh*).
It begs the question: What exactly is "philosophy" anyway? I would certainly hope that you do not have to be a "philosopher" in order to
think, but what is thinking? If you "think" about whether you particularly liked what you ate for lunch, is that the same as thinking about whether your decision in a political election was the morally appropriate one or whether it had any moral bearing at all? What is the difference between honest open-mindedness and fruitless philosophizing?
...but then again, maybe I am overthinking the idea of "thinking too much." Aaah, the irony, neh?
