Many great philosophers doubted their knowledge. [The Paradox of Induction touches on this skepticism][1]

Skeptics say that all knowledge and scientific progress is based on inductive logic, which is fallible. That it is arrogant to presume we know anything or we’ll ever comprehend the growing complexities of the world around us. That even if we conduct experiments and analyze the results 10, 100, 1000 times, there is no guarantee the 1001th result will be the same

Is there no objective or absolute knowledge? No foundational, fact of the matter or right answer? Is the knowledge we have, about what happened in the past, what the universe is made of, who we are, etc, just conviction, just convention, just ideology, just a badge of power, just the rule of the language game we play, just the product of an irrepressible disposition to lie to ourselves that we have discovered out there in some external, objective, mind-independent world what we invented ourselves, out of instinct, imagination and culture? Or is there an objective or absolute knowledge? What evidence is there for the existence of objective, absolute knowledge? 

Are there any arguments against the belief that all we know is that we know nothing?
