In some previous thread discussions I have had discussions about the nature of uncertainty, and to what extent does it exist in the context of apparent certainties. However, the dichotomy between certainty and uncertainty is one which still haunts and plays a role in my imagination and understanding. I see it as an aspect of existential angst, such as that expressed by Kierkergaard in thinking about the unknown. There are many unknown variables in life, especially the dichotomy between opinions.

However, the nature of certainty and uncertainty is an aspect of philosophy discussed by Wittgenstein and many other philosophers, and it may be an important factor in contemplating actions and risk. Wittgenstein said, 'The difference between the concept of "knowing" and the concept of "being certain" isn't of any great importance at all, except where "I know" is meant to mean: I can't be wrong. I a law court, for example, " I am certain" could replace "I know" in every piece of testimony.'

I am writing this thread on the basis of the issue of the 'New Philosopher' titled 'Uncertainty Rules(2021). It includes various thinkers on certainty, uncertainty and aspects of life, like the uncertainty which a person has about when he or she will die. The editor of the volume says,
'the certainty of death in an uncertain life should galvanise us into action to live life to the fullest. We mightn't have much much control over our fate- when we are born, the amount of luck in our lives, and when it will end..'

So, I am asking about how much is certain and uncertain in life experiences and knowledge? What is the tension between the certain and uncertain in philosophical understanding?
