Human compassion allow us to see things from other people's perspective although some might call that empathy. We've based a lot of what we are and what we do as people on compassion towards others. Some might say that our system of morality is based on reducing suffering, something compassion makes us do.
Human compassion informs our understanding of the world <em>by giving us empathy.</em>
Explanation:
By being sensitive about what happens to others all over the world, we, the people, are capable of feeling other's feelings and understanding other's situations. Having compassion for others is essential because we can feel related with others and can put ourselves in their place, and them in ours. Empathy is so important in order to grow as a human being, it allows us to be generous and solidary.
