Above all we need, particularly as children, the reassuring presence of a visible community, an intimate group that enfolds us with understanding and love, and that becomes an object of our spontaneous loyalty, as a criterion and point of reference for the rest of the human race."
-Lewis Mumford (1895-1990)
It helps us to know, from an early age, that we're not in this alone. We crave that love and support from other human beings. This is how we learn about people, and how we learn about ourselves.
