Think how different human societies would be if they were based on love rather than justice. But no such societies have ever existed on earth.
There is no more irritating fellow than the man who tries to settle an argument about communism, or justice, or liberty, by quoting from Webster.
When we ask for love, we don't ask others to be fair to us-but rather to care for us, to be considerate of us. There is a world of difference here between demanding justice... and begging or pleading for love.
