I believe it was Aristotle who thought about this idea, but basically it was that humans are born "incomplete," like one half of a puzzle or something like that, and out in the world somewhere is another person who is the "exact fit," someone who can be your soulmate, lover, best friend, whatever. Personally I find the idea somewhat comforting and inspiring. Encourages people to never give up and such. As the original question and thread title displays, what are your thoughts?
The idea makes it sound as if it's all predetermined. Looking at it that way, it makes it seem almost pointless to go on with life because you don't think you have any control over what happens to you. I do understand you opinion, I just don't think like that I guess.
Personally i don't think that we are as easy as puzzles. I think that we are puzzle pieces who's shape keeps cahange at a certain rate and the person that completes you would be able to change with you. Even though some people might've fit in there at one point they won't later.
I agree with the thought that it's comforting and inspiring. But I don't think there's exactly one person. There might be one person that is a perfect fit to your "puzzle piece" but I think there are other pieces that can fit your piece, even if it's not a perfect fit. Not necessarily a "changing" piece, like daxma said, but someone who can keep you happy. To have the perfect soulmate, best friend, and whatever else is lucky and rare. To have one person be all of those is even luckier and rarer.
There are personality traits that are more "compatible" to others but I'm wary of any view or opinion which defends the existence of such a thing as perfection, especially when it deals with something as complex as human relationships. No, I'll just stick to the belief that some people are better off with eachother than with others but I wouldn't take it as far as to say that they're lock and key for eachother.
I don't believe in "that one true person", because that implies that if you find this person, and the person dies or something, then you will not be happy with anyone else for the rest of the life because you lost the other half of your puzzle. I believe that certain people are good for one another if their personality traits complement each other, and if you find someone like that, then by all means be with them. However, if you lose them, don't act like you're never going to find anybody else. It will be hard, yes, but not impossible.
Hmm, interesting but I don't believe in it fully. The concept that everyone has a partner who can fill in all the empty parts of what you are...I don't think thats really possible. We all have a void, an emptiness of some sort. ANd its as simple as finding someone else who can fit those empty bits and life is a paradise? I'm not sure.
