Logic Textbook composed of excerpts from the volume
by Witold Marciszewski
Logic from a Rhetorical Point of View
Walter de Gruyter, Berlin / New York, 1994

The chapters as listed below are selected from the mentioned volume, with kind permission of the Publisher (his letter of 24 January, 2005). These are to assist study of logic.

The main plot of the book is the feedbak between two processes: the reasonings being verbalized, symbolic, some of them even formalized (algorithmized), and the reasonings unverbalized, intuitive, even not fully conscious. The latter are supposed (John von Neumann's inspiration) to be a function of neural code, here called (Ch.7) the internal logical code in human bodies. The former is the subject matter of symbolic logic, hence a fairly extensive exposition of Logic, and also (in Leibniz's spirit) of Artifical Intelligence (Ch.7 and 8); these parts are reproduced here in electronic form.

The remaining chapters (omitted here: 1, 2, 3, 9, 10, and Postscript) deal with the said feedback as essential in rhetorical activity. Speaker's or writer's efficient acting upon an audience requires a clever combination of the both kinds of means, those being symbolic, including symbolic logic, and those operating beyond langauge. Just in this way, if we wish to influence the minds of other people, we can try to match the enormous complexity of mental phenomena -- as ingeniously noticed by Blaise Pascal (his idea of esprit de finesse), being the hero of Chapter One.

The selected chapters:
