The Problem of Induction/Causality/Uniformity of Nature All science rest upon inductive inference. It takes something that we have experienced in the past and projects it into the future. Here is an example, you get up in the middle of the night and you walk around and stub your toe. The next night you get up in the middle of the night and walk around and you??re careful to not stub your toe again. If stubbing your toe last night hurt, stubbing your toe tonight will hurt to. The way things were in the past in terms of causal relationships will be things you encounter in the future too. Can you see why all science depends upon this? If there were no uniformity in the natural world, then all of your scientific experiments would be waste of time. You could learn everything you wanted about chemical reactions on Monday, but on Tuesday everything would be different. Induction is simply the view that the future will be like the past. Future relationships between events will resemble past relationships between events.
What will happen if I let go of this marker? Let's say that you have never seen this experiment done before. The good philosopher will say that we have no way of knowing. I will now do the experiment. Watch closely! (it drops). We are now going to do a second experiment. You now know that one time, 20 seconds ago, this fell when I let go of it. What will happen when I let go of it this time? You don't know. The reason you don't know is because you have no basis for inductive inference. You have no basis for knowing the future will be like the past. You say, —well that was 20 seconds ago with the same conditions.?? But you are assuming under the same conditions that one event will lead to the same event. You are assuming the uniformity of nature.
