"Education is what remains after one has forgotten what one has learned in school." 
Albert Einstein

Humans aren't as good as we should be in our capacity to empathize with feelings and thoughts of others, be they humans or other animals on Earth. So maybe part of our formal education should be training in empathy. Imagine how different the world would be if, in fact, that were 'reading, writing, arithmetic, empathy.' Neil deGrasse Tyson
