Neste livro Schopenhauer apresenta 38 estratégias sobre a arte de vencer um oponente num debate, não importando os meios, utilizando a maior ferramenta que possuímos; a palavra. É possível recorrer a estes estratagemas, lícitos e ilícitos, para 'obter' razão, e defendê-la quando ela estiver do nosso lado ou conquistá-la quando estiver do lado do adversário. Com frieza classificatória, Schopenhauer indica 'os caminhos oblíquos e os truques de que se serve a natureza humana em geral para ocultar seus defeitos'.

Futurists insist that AI will soon eclipse the capacities of the most gifted human mind. What hope do we have against superintelligent machines?

Logic is often perceived as having little to do with the rest of philosophy, and even less to do with real life. In this lively and accessible introduction, Graham Priest shows how wrong this conception is. He explores the philosophical roots of the subject, explaining how modern formal logic deals with issues ranging from the existence of God and the reality of time to paradoxes of probability and decision theory. Along the way, the basics of formal logic are explained in simple, non-technical terms, showing that logic is a powerful and exciting part of modern philosophy.

Ludwig Wittgenstein is één van de belangrijkste denkers uit de 20e eeuw en zijn filosofische werk omvat vrijwel het hele menselijk denken en handelen, met nadruk op de logica. Weinig mensen echter weten dat muziek een hoofdrol speelde in zijn leven. Hij groeide op in een muzikale familie, waar grote componisten als Brahms en Mahler over de vloer kwamen. Zelf speelde Wittgenstein klarinet en hij componeerde een muziekstuk, getiteld Leidenschaftlich, dat hij met potlood tussen zijn filosofische aantekeningen krabbelde.

This work sets forth a theory which is speculative in nature, there being no verifying experiments. It is based on the idea of the reversibility of everything in time; that is, that every type of process has its time image, a corresponding process which is its exact reverse with respect to time.

The history of Western thought contains hundreds of statements by philosophers testifying to the use of esoteric writing in their own work or others'. Despite this well-documented history, however, esotericism is often dismissed today as a rare occurrence. But by ignoring esotericism, we risk cutting ourselves off from a full understanding of Western philosophical thought. Arthur M. Melzer serves as our guide in this engaging history of philosophical esotericism. Walking listeners through both an ancient and a modern esoteric work, he explains what esotericism is - and is not. 

Die adjektivische Passiversatzform 'unverständlich' ist transformierbar in den Ausdruck 'kann nicht verstanden werden'. Das Modalverb 'können' hat typischerweise drei Funktionen: Kompetenz, Möglichkeit, Erlaubnis. An jeder schriftlichen Kommunikation sind (sehr einfach ausgedrückt) mindestens drei Momente beteiligt: ein Produzent, Zeichen, ein Rezipient. Wenn ein Zeichen, ein Wort, ein Satz, ein Text als 'unverständlich' bewertet wird, ist fragbar: Warum? "Die Fragmente von Friedrich Schlegel sind unverständlich." Mögliche Gründe: (1) Der Autor hat nicht die Kompetenz, sich verständlich mitzuteilen.

"Philosophy is not a theory," asserted Austro-British philosopher Ludwig Wittgenstein (1889-1951), "but an activity." In this 1921 opus, his only philosophical work published during his lifetime, Wittgenstein defined the object of philosophy as the logical clarification of thoughts and proposed the solution to most philosophic problems by means of a critical method of linguistic analysis.

Philosophical Investigations was published in 1953, two years after the death of its author. In the preface written in Cambridge in 1945 where he was professor of philosophy he states: ‘Four years ago I had occasion to re-read my first book (the Tractatus Logico-Philosophicus) and to explain its ideas to someone. It suddenly seemed to me that I should publish those old thoughts and the new ones together: that the latter could be seen in the right light only by contrast with and against the background of my old way of thinking.’
