Beautiful song, in a way it is kind of a love song. Essentially he is wondering whether, after all he has experienced in "all of the seasons", if this other person really feels the same way about life and the questions that surround their existence. Perhaps the character is saddened though because after "tasting [your] answers]", he finds his body is weak for the person and for the truth (unable to attach back into reality because he finds it too painful). In conclusion, the song is saying he is not the one for them because he is simply too emotional because he has seen the truth (or has read too far into their relationship - "eyes that know why?"). Rush put a lot of context into their lyrics, I don't know what anyone else thinks; I just know I like the song. Peace.
