摘要: Should the title of this paper prompt you to ask, “What is logic perception?”, there an answer at hand. I shall argue here that our perceptual terms a branch modal logic.1 In saying this, mean by ‘perceptual terms’ both such words as ‘sees’, ‘hears’, ‘feels’, etc., which involve reference one particular sense modality, and ‘perceives’, are neutral in respect. By logic, not only ‘necessary’ ‘possible’ but also all other can be studied same ways they. Among these most usually said express propositional attitudes, including ‘knows’, ‘believes’, ‘remembers’, ‘hopes’, ‘strives’, etc. What common notions extended term will partly explained later.2
