Kuhn's work The Structure of Scientific Revolutions, to which Emerson refers, is indeed a must read. It is one of those very rare books which can be found in almost all top 100 must read books..
As for the ever increasing accuracy with which we describe reality, well.. is this really a problem? Employing objective observation and critical thought, as well as recognizing that objective reality exists and can be described, does not require omniscience or any pretense of such (though perhaps ironically that presumption is almost always found in the subjectivity camp). Instead it recognizes that we can perceive reality and to the extent to which we are successful, proved in many ways including the functioning of technology as in my previous examples, we can describe it. As long as we are careful, objective, and reasonable (literally able to use reason) our progress is in one direction: ever towards more accuracy. When we abandon or deny these, well we get Westboro Baptist Church, the KKK, and other thankfully less harmful ills.. such as the roof caving in on my head were I to ignore reason and reality in building my home..
