The Tapping Game

The tapping game is when I tap one time, you tap two times, and when I tap two times, you tap one time. Children play this game sixteen times, mixing up the times that children are asked to tap once when the experimenter taps twice, and tap twice when the experimenter taps once. In other words, the rules of the game keep changing, and the children need to apply their focus and attention to follow what’s going on. Blair says: What happens with four-year-olds is, in general, they’ll hang in...

 Imagining the Primitive Mind

AND now let us indulge in a very interesting speculation; how did it feel to be a man in those early days of the human adventure?

Those were days long before the written record of any human impressions, and we are left almost entirely to inference and guesswork in our answers to these questions.

 Bayes and Richard Price on Predictions

It concerned how we formulate probabilistic beliefs about the world when we encounter new data. Price, in framing Bayes’s essay, gives the example of a person who emerges into the world (perhaps he is Adam, or perhaps he came from Plato’s cave) ...

 Nature contains no one constant form.

With respect to those who may ask why Nature does not produce new beings? We may enquire of them in turn, upon what foundation they suppose this fact?

Know they if, in the various combinations which she is every instant forming, Nature be not occupied in producing new beings, without the cognizance of these observers? Who has informed them that this Nature is not actually assembling, in her immense elaboratory, the elements ...

 Science Takes Us Beyond Our Experience

The aim of scientific thought, then, is to apply past experience to new circumstances; the instrument is an observed uniformity in the course of events. By the use of this instrument it gives us information transcending our experience, it enables us to infer things that we have not seen from things that we have seen; and the evidence for the truth of that information depends on our supposing that the uniformity holds good beyond our experience.
