James's 'terrible algebra'

“You are right in your consciousness that we are all echoes and reverberations of the same, and you are noble when your interest and pity as to everything that surrounds you appears to have a sustaining and harmonizing power. Only don’t, I beseech you, generalize too much in these sympathies and tendernesses — remember that every life is a special problem which is not yours but another’s, and content yourself with the terrible algebra of your own. Don’t melt too much into the universe, but be as solid and dense and fixed as you can." 

Henry James.
