The word “real” (from the Latin “res” = thing) was coined in the 13th century to signify “having Properties” (Pierce. 1958, p. 358), whereas a “model” refers to an analogical representation, the structure of which should correspond to the structure or properties of that which it represents. For Scudder the mind is a system of models and each mind develops different models. We all have a different reality in mind and so we each live in a slightly different world (Scudder, (...) 1975). Hence the real nature of the model and the model nature of reality are often indistinguishable. A snail, for example, when exposed to four tactile stimuli per second (with a rod on his belly) will be compelled to crawl upon that non-existing coherent spatial surface (Brecher, 1966). For the snail four tactile stimuli per second correspond to, or are isomorphic with, the structure of a spatial surface, but it is impossible for the snail to “know” which of the two structures is real.

Research in animal behavior begins by identifying what animals are doing. In the course of observation, the observer comes to see animals as performing a particular activity. How does this process work? How cn we be certain that behavior is identified correctly? Wittgenstein offers an approach to these questions. looking at the uses of certainly rather than attempting to find rules that guarantee it. Here two stages in research are distinguished: first, watching animals, and second, reporting the results to other (...) scientists. Certainly about what animals are doing, has different uses at each stage. (shrink)
