Any process which is not completely i.e. from start-to-end, natural, involves 2 causes – the commonsensical cause and the scientific cause. (These aren’t what these names make them seem).
Suppose I dip a cloth in flowing water, it will get wet. Now, if someone asks – why did the cloth become wet? The commonsensical everyday-life answer is that because someone dipped it in flowing water. The scientific cause is – water coming in contact + the materials’ science.
The former has significance because if that action would not have been done, the further steps wouldn’t have taken place – the scientific process wouldn’t have been set in action.
The latter has significance because of the generality of explanation it provides (as well as predictability in other variable scenarios).
Commonsense cause has to be just at the right spot since one may say that because the cloth was bought from the market the cloth is wet since that is also one step which if wouldnt have been done, the further steps wouldnt have happened, and it would not have become wet. But, at the same time, this might be relevant, in some particular context. So commonsense cause is variable according to context.
