The paper takes up Wisdom's (1964) little known but significant critique of Bion's book, Learning From Experience. While Wisdom appreciates Bion's clinical and theoretical innovations, he criticised the at times confusing structure of themes that were not sufficiently segregated, the extraneous use of mathematical notation, and the scientific/deductive part of Bion's monograph. In deploying a crucial distinction from Wisdom's critique, one that separates the scientific/deductive aspect of Bion's work from its clinical/inductive trajectory, the author offers an approach to reading Bion's complex text.
