At pains to define liberty, that most resolute of indefinables, our minds fall back on spatial images; on birds, sailboats, and mountains; the untethered balloon, the blue sky, the nude figure.

The goal of discoverers is not to outdistance their peers, but to transcend themselves.

Free men and women... can think across time, viewing their own lives, inclusive of past, present, and future, as architectural wholes, static in mental space. They can therefore see, as others cannot, the cracks and buttresses of repeated action, the points of stress, the established framework. They are not perfect; but they are less imperfect than we by a full dimension of being.

The extent to which we live from day to day, from week to week, intent on details and oblivious to larger presences, is a gauge of our impoverishment in time.

You may cure yourself of a depression by forcing yourself to perform, in rapid order and with excruciating concentration, half a dozen or so unpleasant chores, especially if they have long been postponed. This is a kind of homeopathic purgative, a treatment of like with like.

That morning I experienced vividly, if almost subliminally, the reality of change itself: how it fools our sentinels and undermines our defenses, how careful we are to look for it in the wrong places, how it does not reveal itself until it is beyond redress, how vainly we search for it around us and find too late that is has occurred within us.

The limitation in our ability to perceive broad distinctions in scope can be applied to our moral and temporal responses.... We agonize over a dinner menu, or have engine trouble on the way to work; and for seconds or minutes our cosmos shrinks to a miniscule volume of being, an epic of cheese sauces or tragedy of fanbelts.
