"Thomas Luckmann became one of the leading figures in what became to be called the “new” sociology of knowledge. His “Social Construction of Reality”, co-authored with Peter Berger in 1966, influenced many social scientific disciplines, the humanities and various academic movements, such as “social constructionism”, “social constructivism” or the “new institutionalism”. The “Invisible Religion”, published in 1967, became immediately a classic text in the Sociology of Religion. It formulated one of the most inclusive theories of religion as being based in human’s capacity to transcend the biological organism. After his “Structures of the Life-World”, co-authored with Alfred Schutz, he added a differentiated concept of transcendences which was included in the later versions of the “Invisible Religion”."
