Reactions to the question “Is There Purpose in Biology?” are likely to vary greatly. One reaction will be “of course not”: watch your favourite natural history programme and it’s obvious that chance rules. Some animals get lucky and do well, others get eaten young, and there’s no overall rhyme nor reason to it. Others responding to the same question, most likely coming from a religious worldview, will respond “of course”: God has an overall purpose for everything, including biology. Others, perhaps the majority, are more likely to say: “Well it all depends on what you mean by purpose…” Continue reading
In the summer of 1905, an obscure patent clerk, recently turned physicist, radically changed our view of the world with one mathematics equation, E= mc2. With this simple, but ultimately profound, statement Albert Einstein showed that matter and energy were simply different forms of the same thing. The ramifications of this revolutionary concept were enormous, ultimately sowing the seeds for the nuclear age that emerged in the 1930’s and 1940’s. Continue reading
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
