Discovering Ourselves Through Passions of Other People
When a natural discourse paints a passion or an effect, one feels within oneself the truth of what one reads, which was there before, although one did not know it. Hence one is inclined to love him who makes us feel it, for he has not shown us his own riches, but ours. And thus this benefit renders him pleasing to us, besides that such community of intellect as we have with him necessarily inclines the heart to love.
Blaise Pascal, in 'Pensees'
