In his Faraday seminar on teleology (part 1 here), Dr Harvey McMahon suggested that we use more than one type of language to talk about biology. If language is a lens that gives us a certain perspective, then it would be useful to have more than one type of lens in our toolbox. The lens that McMahon suggested we use a little more is teleology, or purpose. He gave three examples of how teleological thinking can be applied.
The stochastic nature of biology
‘Stochastic’ behaviour involves a certain amount of randomness. You could predict the outcome of a stochastic event using statistics, but you would never be 100% certain what was going to happen. That is the nature of most biological processes. The question is, if we were smart enough to study biological systems down to the atomic level, would we find that they are actually completely predictable? Would knowing all the variables make 100% predictions possible? And if we could predict every process in our bodies and brains, would there be room for human decisions? Continue reading
