we have had this discussion before

But it is one of those I like having. Maybe I am predisposed to like indefiniteness. Or maybe because most if not our knowledge is provisional and open to revision when our ways of gathering data improves or when a challenge is mounted on current knowledge that shows our understanding of a given topic has been wrong or misguided.

It could also be possible that whilst some questions have been settled, there is reluctance to accept the answers. And this reluctance could be sustained by the fact many believe the old answers without reflection or are afraid that accepting the new answers would turn their worlds topsy turvy. For example, it is settled that asses never spoke nor snakes walking upright or men fish eating men and surviving whole for 3 days under water or that some man was born without a father and then committed deicide. These are just a few of the old answers that we cannot accept as true knowledge.

Tell me what you think.
