Your partner has well-defined ideals when it comes to their values -- the beliefs that make them the person that they are. All their life, they've been looking for another person who complements them in those ways; someone whose values don't necessarily match up with theirs point for point, but whose beliefs are at least as developed and well-founded as theirs are. Truthfully, matching values doesn't hurt!
Deep down inside yourselves, you both know that's the only way that a long-term relationship could work for you -- if your lover had a soul that was searching for truth, as yours is; if spirituality was important to your lover, as it is to you. Well, this relationship might just be the very one you've been looking for all along. You find that you share a meeting of the minds on all the important levels -- spiritually, sexually, socially and so on. You both adore talking about your philosophies of life together -- in fact, some of your first and best encounters could involve staying up much too late, just talking on the phone or exchanging emails in which you discuss all the ideas that are important to you, all the questions you have about life and the universe. Gradually, you both start to realize that in each other, you've found someone who can accompany you along your path in life -- your search for truth and beauty, and your living out of your philosophical and spiritual ideals.
