Children teach us that love is, in its purest form, a kind of service. The word has grown freighted with negative connotations. An individualistic, self-gratifying culture cannot easily equate contentment with being at someone else's call. We are used to loving others in return for what they can do for us, for their capacity to entertain, charm or soothe us. Yet babies can do precisely nothing. There is, as slightly older children sometimes conclude with a sense of serious discomfort, no 'point' to them; that is their point. They teach us to give without expecting anything in return, simply because they need help badly - and we are in a position to provide it. We are inducted into a love based not on an admiration for strength, but on a compassion for weakness, a vulnerability common to every member of the species and one which has been and will eventually again be our own. Because it is always tempting to overemphasize autonomy and independence, these helpless creatures are here to remind us that no one is, in the end, 'self-made'; we are all heavily in someone's debt. We realize that life depends - quite literally - on the capacity for love.
