The oak axle creaked loudly under her weight [ Il. 5.838]. But how can something weightless cause the effects of weight? They say that the things which participate must be regarded as analogous to whatever it is in which they participate. Although the god being participated in is one, the soul participates in one way, the intellect in another, the imagination in another, and perception in another: they participate untwistedly, indivisibly, in shapes and through experiences respectively. That which is participated in is uniform according to its basic existence but diverse according to its participation [i.e. that which participates in it]. It is imagined by the participants sometimes in one way and sometimes in another owing to their weakness; and that is not all: even weightlessness seems to cause weight.
