Yes, but there are also problems with only having uncertainty:Gokul43201 said:All I'm saying is that assumption of the 'ability to do anything' leads to logical inconsistencies.
Here is a quote of Richard Feynman:
Feynman also appears to be expressing a mathematical paradox, basically in the form of a statement:
"I can live with doubt and uncertainty and not knowing. I think it’s much more interesting to live not knowing than to have answers which might be wrong. I have approximate answers and possible beliefs and different degrees of certainty about different things, but I’m not absolutely sure of anything. "
We can only be certain that we are not-certain
X iff not-X
