What does man is an animal suspended in webs of significance he himself has spun mean?

Is a quote by Clifford Geertz via Max Weber from his book Interpretation of Cultures. Essentially, Geertz is referring to the influence of culture on human beings. Webs of significance could be taken to mean "culture." In this sense, Geertz is saying humans have the ability to create and modify their cultures, but that their cultures then serve to define the world around them through categorizations and methods of understanding enforced by cultural institutions. Humans cannot escape their cultures. They create them and are suspended in them. The world is defined through their cultures.

Heisenberg made a wonderful statement that is similar in meaning. To paraphrase, "We must remember that what we observe is not nature itself, but nature exposed to our methods of questioning." Culture gives us these certain methods of questioning which we then use to construct our view of the world around us.
