I am not saying to abandon pursuit of knowledge,but like i stated in an earlier comment the number 0 for example exists to define 'nothing' and was not considered useful up until a few hundred years ago I believe. In the same way,if you can define "unknowable" as a value and assign it to certain variables,perhaps more knowledge and truth can be understood?
