The prolegomenon inquires into the notion of oikology, a term being a compound of the two words 'econony' and 'ecology' with the Greek oikos as their main root. Oikology, meaning 'household studies,' focuses upon such notions as 'home,' 'shelter,' 'place,' 'space,' 'localness,' 'community,' and 'rootedness.' The preliminary part refers to Simone Weil's thoughts on the notion of 'rootedness' (enracinement) which is the human soul's innermost and most familiar, yet not easily definable, need. Therefore, 'rootedness' appears an integral part of any oikological discussion which concerns the house, home, space, and man's surroundings, whereas the human emerges as the one interrelated with that which surrounds him. The house is the sphere which holds the private and the public, the individual and the communal together. Yet it is a multifaceted notion, uncovered as the dwelling-place of man, an inhabited space which joins the human with the world. In oikological terms, the house provides an essential view of the dialectics between a shelter, and its relations to the terrain it is located. Therefore, the house is a dwelling-place of the I and the non-I as the I goes deeper down in his question of the 'where' of his being.
