Before my discovery of photography, I recall two pivotal lessons. One high school professor taught me why questioning leads to knowledge and how to distinguish observations from prejudices. One university professor showed me the limits of measure and of intellectual models. Soon after my schooling, yearning to widen my experience, I realized I needed new tools. I knew that intellectual reflection alone was not sufficient to acquire knowledge and wisdom. Two fundamental questions have been guiding my research: What is reality? How does my free will interact with the rest of reality? This section explains how photography has been helping me in the search for union.
