Gotcha! Thanks for the interesting post, Hippyhead! :smile: My immediate thought is that if someone is quickly scanning through another's ideas simply to find fault in those ideas, then that person isn't very interested or open to considering those ideas in the first place. Of course it helps to point out contradictions and other flaws in one's thinking, but to effectively do this, you also need to thoughtfully consider how all of the ideas, arguments, etc. relate or don't relate to each other, and why the person might have proposed them. This is not easy to do if you're just briefly glancing at what he or she wrote. In addition, the problem with the ideas might not even be that they are wrong per se, but that they have not been elaborated upon enough or backed up with examples or evidence.
As for my thoughts on the discipline of philosophy in general, I don't believe it is pointless just because people can't agree on everything. It is noble to search for the truth for the sake of understanding it to live a meaningful life, and since our experiences, intelligence, wisdom etc. vary, we will have different views. That doesn't take away from the meaning we find in our own beliefs and why.
