Is the knowledge of an absolute kind or can it be developing? Is there any limits of this development?

Answer 1

strictly speaking there is no such thing as absolute knowledge. that would require absolute truth, and that is provided only by religion... and can and should be challenged...

what you know, is actually only what you hold to be true. the degree of resemblance to actual reality depends on the accuracy of your sources, and of your conclusions from that information, if in fact you made any, instead of just taking it for granted.
either way, new information calls for a re-evaluation of the things you hold to be true. and just as new information comes streaming in constantly, so is the development of your knowledgebase a constant process. and since no truth is ever absolute, there is no limit or end for that process.

or should be. the development of your knowledgebase is unfortunately not automatic, but a constant effort, that all too many people dont care (or dare) to make.

Answer 2

Knowledge is not absolute. If it were, there would only be one answer to a question. Knowledge is expandable, there are no limits.
