4.Left And Right Have Been Confusing Philosophers For Years
How would you explain the concept of left and right to someone who had no idea what those words meant? Would you explain it in terms of your relative position to a well-known stationary landmark? Or maybe you'd think outside the box and refer to the rotation of the Earth or something comparably massive and unchanging. But what if you were talking to an alien whose planet rotated differently to our own, or one who didn't have eyes? It's a question that has been intriguing philosophers for years because, without an agreed upon point of reference, it's incredibly difficult to define what left and right actually are.
For example, consider the work of German philosopher Immanuel Kant, who once said, "Let it be imagined that the first created thing were a human hand, then it must necessarily be either a right hand or a left hand."
However, with only one hand, it's impossible to explain which hand it is without another one present. Think about it for a second-right and left hands are clearly very different from one another, but if you were to describe them, the deions would be literally identical because they're the same. Only they aren't because, as Kant himself put it, a left hand can't fit into a right-handed glove, so there is a difference between them. However, said difference is practically impossible to put into words without the other hand being present.
If you think we're over-complicating this, we should point out that there is literally a 400-page book on the philosophy of right and left, aptly called The Philosophy Of Right And Left. That's more pages than it took to work out 1 1=2.
如果你认为我们夸大了这一问题的复杂性，那我们应当指出，关于左和右的哲学还真有一本400多页的书，名字也很贴切，就叫《左与右的哲学》(The Philosophy Of Right And Left)这可比验证1 1=2所占的页数还要多。
