"I think part of the appeal of mathematical logic is that the formulas look mysterious - You write backward Es!"

Hilary Putnam's quote suggests that mathematical logic has an appealing quality to it, as the solutions appear to be strange and complex. This complexity is highlighted by the use of backward Es, which are symbols used to represent rational statements. Putnam's quote suggests that the intricacy of mathematical logic becomes part of its appeal, as it can be seen as a difficulty to be fixed. This obstacle is most likely to be appealing to those who have an interest in analytical and logical thinking. Putnam's quote likewise suggests that the use of signs and formulas can be seen as a form of art, as the backward Es can be viewed as an imaginative method of expressing rational declarations. This quote implies that mathematical reasoning is an intriguing and interesting topic, as it can be viewed as a form of innovative expression along with a challenge to be solved.
