"The Roulette, or organ of chance and habit, is an analogical machine for playing a modified game of marbles. It is the organ the Clown uses to test the hypothesis of morphic resonance, the transmission of form and behaviour through repetition in time. This is a notion the maverick geneticist Rupert Sheldrake explored, using what C.H. Waddington called chreodes, by which he meant developmental pathways in nature, somewhat akin to the philosophical idea of entelechy (the process of becoming or of being actual); a chreode is a path of potentiality. The hypothesis of morphic resonance proposes, among other things, that entities in nature exhibit fields of form, quite unlike fields of force, and transmit information without the use of energy. The morphogenetic field irradiates likeness. It is a rhyming theory of things. Roughly it amounts to this: the repetition of an event induces the seed of habit, and the likeness of that habit can in turn be transmitted through the fabric of nature..." (1)
