The scientific method is great! It involves the collection of data through observation and experimentation, and the formulation and testing of hypotheses (or guesses). For example, if I want to discover if a tennis ball bounces higher than a basketball I can design a scientific experiment to find out the answer.
Unfortunately it doesn’t always work. Some questions have no answer. One of my favourite philosophical questions is the ‘Brain in a vat‘. In short, how do you know that you are sitting there at a computer on Earth reading this post? How do you know that your brain is not somewhere completely different being fed a series of electrical stimulations by a supercomputer which is fooling you into thinking your on Earth?
So my question is – how do you know you are where you think you are? And if you think you know – PROVE IT!
