Love should be taught in schools, because the vast majority of us are pretty ignorant of it.
There is a spiritual aspect to love. Some may describe it as following God's will, others may call it something else, but it's there. Maybe this spiritual aspect is another evolutionary trick for the continuation of the species, but it's real and important none the less. Another way to say this, perhaps, is that it's part of Maslow's heirarchy of needs, and it's near the top.
Love does is real, and it does matter.
