Through this curious analogy, Wittgenstein is trying to point out that the beetle is very much like like an individual’s mind. No one can know exactly what it is like to be another person or experience things from another’s perspective (look in someone else’s box), but it is generally assumed that the mental workings of other people’s mind are very similar to our own (everyone has a beetle which is more or less similar to everyone else’s). However, it does not really matter – he argues – what is in the box, or whether everyone has a beetle, since there is no way of checking or comparing. In a sense, the word “beetle” – if it is to have any sense or meaning – simply means “what is in the box”. From this point of view, the mind is simply “what is in the box” – or rather “what is in your head”.
