Truth be told, the two of you probably don't have a lot in common when it comes to what you value. While you may share some commonalities in religion, political orientation, or other affiliations, the way you think about the world and what is important is fundamentally different. If you agree on matters of morals and ethics, it's probably for very different reasons.
You are deeply practical, logical and emotionally hands-off. It's not that you don't care about others; just that you don't prioritize the act of caring as much as your counterpart does. When you are concerned with other people, you typically feel that a pragmatic solution is the best one. You might spend an afternoon helping a needy friend fix a broken window, or donate money to a local school. But typically your instinct to help is out of a sense of dutiful social responsibility. Usually, once you've helped, you move on with your day. Fixing problems is a central part of your value system; caring for others is not.
In contrast, the values system of your counterpart is based on a deep empathy and compassion for others. They can't watch the news without feeling the pain of starving children; those commercials with sad kitties at the pound were made for people just like them. Because compassion is such a big part of who they are, it motivates their biggest decisions in life. Their career was probably chosen because it is consistent with their values and the changes they want to make in the world. Their friends are probably people who feel the way they feel about the issues that are dear to their heart.
You may find yourself somewhat disbelieving of your counterpart's approach when discussing values that are important to you. They are deeply idealistic and easily imagine how the world could be a better place. But to you, one of life’s practical problem solvers, their ideas may seem pie-in-the-sky or romantic, and lacking in all practical application in the here and now. You tend to be suspicious of new ideas and blunt in your communication, which in practice means that you'll often unceremoniously shoot down your counterpart’s suggestions with "That would never work in the real world" or "What planet are you on?!"
On the other hand, because you are so different, you have the opportunity to introduce one another to new ways of thinking. You value tradition and the wisdom of experience much more than your counterpart does, and you can help them to see the merit in looking to the old ways. And if you're willing to step outside your comfort zone, your counterpart has the ability to help you become softer, gentler, and more emotionally in tune.
