Science: The question of its limits

Science is my theme in this paper devoted to a celebration of Susan Petrilli's pathbreaking book, Signifying and Understanding. Why science? Because it has a long conflicted history, yet it is the source of the greatest creative works of humans. I compare Welby's humanistic and unbounded science together with that of Peirce to the bumpy up and down that marks the American anthropological story of science. Welby describes clearly her modern and foresighted program. I believe that we need to accept hers and Peirce's paradigm for global semiotics.
