爱的意义
古往今来，许多文化学者、科学家、哲学家、心理学家、人类学家及社会学家们，都想说清楚“爱”。都想给爱以恰当的或准确的解释和定义。
爱，即人类主动给予的幸福感，主动地以自己所能，无条件尊重、支持、保护和满足他人无法独立实现的人性需求，包括思想意识、精神体验、行为状态、物质需求等。爱的基础是尊重。爱的本质是无条件地给予，而非索取和得到。爱是纯正的正义。
所以，爱是一种发自于内心的情感，指的就是对某个人或某个事物有纯洁而深挚的感情。这种感情所持续的过程也就是爱的过程。通常多见于人与人或人与物。

本回答被网友采纳随着社会的日益复杂，越来越多的人被很多诱惑或其他一些物质方面所蒙蔽，从而忽略了最真挚的感情，爱。许多人都怀疑爱的存在。我完全不同意他们的观点。前几天，我看了《北京爱情故事》这部电影。我意识到爱是什么，还有原来它就在我们身边。
First of all, love is put one's heart and soul into her shoes. If you love someone, you will do everything for her; you will think on her side. You will reject all the temptations that can make you live better, just because you don’t want to hurt her. Secondly, love is forgiveness. No matter what the other one do to you, you will forgive her at last. You won’t treat her eye for eye. Although what she has done hurts you so much, you won’t do the same thing to, because you love her. Thirdly, love is growing old together. The outside word is so colorful, but what you want is to grow old with her together and treasure every minute with her. What’s more, you will leave a place for her forever in your deep heart, even she has passed away.
首先，爱是全心全意为他着想。如果你爱一个人，你会为她做任何事；你会站在她的角度想问题。你会全部拒绝那些能让你生活地更好的诱惑，只是因为你不想伤害她。其次，爱是宽容。无论对方对你做了什么，最后你都会原谅她。你不会把她以牙还牙。尽管她所做的已经深深伤害了你，你也不会对她做同样的事，因为你爱她。第三，爱是一起变老。外面的世界很精彩，可是你想要的只是和她一起变老，并珍惜和她在一起的每分每秒。而且，就算她离开这个世界了，在你的内心深处会永远为她留着一个位置。
Love is a kind of emotion that everyone has. It is around us. If we pay attention, we will find it. So, do not lose the faith to believe the existence of love. It is the feeling that every can feel by heart.
爱是每个人都拥有的感情。它就在我们身边。如果我们留意，我们就能找到它。所以，不要失去对爱的存在失去信心。人人都能用心感受到它。本回答被网友采纳
爱是百味而不全是甜蜜...
并不一定是他人眼中的完美匹配
而是相爱的人彼此心灵的相互契合
是为了让对方生活得更好而默默奉献
这份爱不仅温润着他们自己，也同样温润着那些世俗的心
，是在能爱的时候，懂得珍惜
，是在无法爱的时候，懂得放手
因为，放手才是拥有了一切…
请在珍惜的时候,好好去爱
在放手的时候,好好祝福…
真爱是一种从内心发出的关心和照顾，没有华丽的言语，没有
的行动， 只有在点点滴滴一言一行中你能感受得到。 那样平实那样坚定。反之发誓、许诺说明了它的不确定，永远不要相信甜蜜的话语。用心去感受吧
Love is inclusive rather than indulgent love is caring and loving is not the favorite blend with each other instead of unrequited love is not all sweet Barilla... The true love is not necessarily fit each other, but people who love each other heart perfect in the eyes of others is to make life better for each other and quietly this love is not enough with their own, but also warm and the secular heart of true love, is to love, to cherish the true love, is being unable to love, know how to let go because, let go is have everything... Please cherish, good to love in go, a good blessing... Love is the concern and care for a given from the heart, no flowery language, there is no grandstanding actions, only bit by bit words you can feel. Such level as determined. And swear, promised to explain its uncertainty, never believe that the sweet words. The heart to feel.
