Abstract interpretation is a computational technique to approximate truth. In other words, it is computationally-based epistemology. It analyzes Soundness, Precision, and Terminability of system specifications. The founders of this methodology are Patrick and Radhia Cousot, whose seminal paper on this subject can be found here. Patrick Cousot also has a short explanation on Abstract Interpretation on a web page Abstract Interpretation in a Nutshell. A more elaborate website on this subject can be found on a website  maintained by Patrick Cousot. A course outline is available here:. A textbook by Patrick Cousot is also available.
