Do we have free will – and do we want it? Thomas the Tank Engine offers clues
The Hindu
A powerful philosophical argument against free will states that since we cannot change the past and the laws of physics, we cannot change the future either.
Are we free or are our actions determined by the laws of physics? And how much free will do we actually want? These questions have troubled philosophers for millennia – and there are still no perfect answers.
But it turns out that a character from a children’s TV series can provide a clue. Thomas the Tank Engine, despite being a locomotive, behaves like a human. He makes decisions and choices. And he is morally responsible: when he does something wrong, he gets punished.
But look deeper and things become complicated. He is an engine. His movements are determined by the shape of the tracks, the workings of his engine and the employees of the railway. So is his free will just an illusion?
Laws of physics explain how a past event results in a future one. For example, if I put a kettle on the hob, the laws of thermodynamics determine that it will boil at a nearby point in the future. If I don’t interfere with the kettle or the hob, there is only one outcome possible: the water will start boiling.
A powerful philosophical argument against free will states that since we cannot change the past and since we cannot change the laws of physics, we cannot change the future either.
This is because the future is just a consequence of the past, and the laws of physics dictate that the past will result in the future. The future is not open to alternatives.

We know birds, animals and insects constantly communicate with each other by making certain sounds. But when we think about plants, we do not ever think of them communicating. Charles Darwin, an eminent biologist, thought otherwise. Plants might appear the quiet, silent and solitary type of organisms but they have a complex way of communicating which is interesting and important for their survival.
