a) A small cube lies in the corner of a room or is<br />

fixed to the ceiling.<br />

b) A small cube is placed in front of the larger<br />

one, at one corner.<br />

c) Similar to b), but now there is a cubical hollow<br />

in one corner of the large cube.<br />

And what do we see in Figure 4? A young woman<br />

or an old one? Both are possible. This is also an<br />

example of an illusion of perception.<br />

John Eccles draws conclusions from these. Even<br />

though a diagram can be interpreted in more<br />

than one way, we can be sure of one thing: there<br />

is only a single, unambiguous image on the retina<br />

which is then electrically transmitted to the<br />

brain. Here the optical image corresponds to a<br />

precisely defined neuronal connection – whatever<br />

form that may take. From this Eccles<br />

deduces the existence of another independent<br />

entity which observes and interprets the actual<br />

brain connections. He calls this interpreter the<br />

mind (others might call this the soul).<br />

Brain and mind can exchange information, but<br />

the mind has the freedom to interpret one specific<br />

picture in various ways. This dualism is illustrated<br />

graphically in Figure 6 (World 1 and World<br />

2). World 1 represents the required material part<br />

– the brain, and World 2 depicts the nonmaterial<br />

according to the dualistic view of man.<br />

Figure 6: The dualistic view of man. On the one side we<br />

have the material aspects (the body with all its anatomical<br />

details), and on the other side is the non-material<br />

part (the I, the self, the mind, and the will). Eccles postulates<br />

the presence of a liaison brain, which is “observed”<br />

and interpreted by the non-material part.<br />
