If you're of a certain age, where the value of knowing WV Quine and Wittgenstein mattered, this may help round your thinking.

Very short. Meant for class discussions in the classical English style: be prepared to argue to develop your thinking. Not quite a reference, still...

While the word logic doesn't appear, the use of Lewis Carroll diagrams helps; especially in the meaningful use of the words: "many" or "most." Because of the prevalence of Geometry, these words seem useless, but in "real" logic, they obviously have meaning. This is what attracted me to the book 4 decades ago and why I needed to reread it in this era.

Before the popular books of philosophy of the later 20th century, the understanding of the limits of language, the pointlessness of definitions and deconstruction(!) were well-known. However, categorization was needed for clarity. Towards the end of the very short, less than 100 pages, book, the number of labels of types of arguments gives pause.

In short, the hidden idea in the book: "be precise when absolutely necessary, but understand the limits of words in general."

PT Geach's main book is "Logic Matters." Yes, it does, but I don't think it's taught any longer, like diagramming sentences.

تامس گیچ، شاگردِ لودویگ ویتگنشتاین، فصول مقدّماتی و مختصری درباره‌ی استدلال و صدق و... در کتاب‌اش گنجانده است. از نیمه‌ی کتاب به بعد هم خواننده قدری با منطق محمولی و منطق گزاره‌ای -به شکل کاملاً ابتدایی- آشنا می‌شود. در کل تنها برای کسانی که تصوّر چندانی از استدلال و علم منطق ندارند می‌تواند مفید و جالب باشد
