Susanne Langer is mainly known as the American philosopher who, starting from her famous Philosophy in a New Key, worked in aesthetics and famously saw art as the product of the human mind’s most important, distinctive and remarkable ability, i.e., the ability to symbolise. But Langer’s later consideration of the connection between art and symbol is propagated by an early interest in the logic of symbols themselves. This rather neglected early part of Langer’s thought and her early interests and lines (...) of reasoning, which she somehow abandoned later on to dedicate herself exclusively to the study of art, are the topic of this paper.
