We need a home in the psychological sense as much as we need one in the physical: to compensate for a vulnerability. We need a refuge to shore up our states of mind, because so much of the world is opposed to our allegiances. We need our rooms to align us to desirable versions of ourselves and to keep alive the important, evanescent sides of us.

We depend on our surroundings obliquely to embody the moods and ideas we respect and then to remind us of them. We look to our buildings to hold us, like a kind of psychological mould, to a helpful vision of ourselves. We arrange around us material forms which communicate to us what we need — but are at constant risk of forgetting what we need — within. We turn to wallpaper, benches, paintings and streets to staunch the disappearance of our true selves.

The attentions of others matter to us because we are afflicted by a congenital uncertainty as to our own value, as a result of which affliction we tend to allow others' appraisals to play a determining role in how we see ourselves. Our sense of identity is held captive by the judgements of those we live among.

By travelling across frontiers, on horseback and in the imagination, Montaigne invited us to to exchange local prejudices and the self division they induced for less constraining identities as citizens of the world.

People who hold important positions in society are commonly labelled "somebodies," and their inverse "nobodies"-both of which are, of course, nonsensical descriptors, for we are all, by necessity, individuals with distinct identities and comparable claims on existence. Such words are nevertheless an apt vehicle for conveying the disparate treatment accorded to different groups. Those without status are all but invisible: they are treated brusquely by others, their complexities trampled upon and their singularities ignored.
