I would say that this remains the case with any sort of explorative thought, any progress in any field of thought will tend to leave some questions unanswered and if the progress has been major then there will be many questions.
At least we know what these problems are there, and we are fixing them as we go. One idea that can stem from the above statement, is that explorative thought is wrong and that we should accept the world as it is, but one of the defining things about humans is the want to explore new concepts and ideas. The reason for advancement accross the last decades and even centuries is the simple fact that humans want to know more about their enviroment, even if this raises more issues, at least there has been some advancement and some of the problems have better fixes. I put a question to you, Can humans afford not to think exploratively? Can we really risk becoming ignorant and not questioning our surroundings if we are to survive as a species?
Anyway, sorry about my wierd philosophy stuff :nuts: and the debating lingo (I had a debate last night, and I'm still thinking debating).
