Part of my conclusion from my undergraduate thesis on archaeological theory...........

As time progresses, and we continue to check and reference established theories with new methods of critique, scientific advances, and more data from other sources, we will see how well theories can stand when put in relation to the world around us. We will always have to go back and check the work done before us because every time we look at it, we gaze from a different viewpoint, and its important to keep looking at a theory because we continue to see it in a new light that will either further support it, or raise questions that need to be addressed.
My only concern as we set out on our path of self-discovery through the past, inching forwards towards a more comprehensive understanding of our beginnings is that we will exhaust our data, our ability to find and excavate new sites before we can reach a honed and accepted method of archaeological discourse. A place where different fields of thought, theories and data will all work collectively in critically tying together the threads of our past into a tapestry of learning and achievement. We should view Archaeology as archaeology. Borrowing from other fields as seen fit in the course in inquiry, and acknowledging new methods that can be checked and appropriated a proper place without bias.
