Posterior Analytics is the fourth of Aristotle's six texts on logic which are collectively known as the Organon (Instrument). Posterior Analytics deals with demonstration, definition, and scientific knowledge. Demonstration is distinguished as a syllogism productive of scientific knowledge, while Definition is marked as the statement of a thing's nature, a statement of the meaning of the name, or of an equivalent nominal formula.

The Novum Organum is a philosophical work by Francis Bacon published in 1620. The title translates as new instrument. This is a reference to Aristotle's work Organon, which was his treatise on logic and syllogism. In Novum Organum, Bacon details a new system of logic he believes to be superior to the old ways of syllogism. For Bacon, finding the essence of a thing was a simple process of reduction, and the use of inductive reasoning . . . This work was critical in the historical development of the scientific method....

The Discourse on Method is best known as the source of the famous quotation “cogito ergo sum”, “I think, therefore I am.” …. It is a method which gives a solid platform from which all modern natural sciences could evolve. With this work, the idea of skepticism was revived from the ancients such as Sextus Empiricus and modified to account for a truth that Descartes found to be incontrovertible. Descartes started his line of reasoning by doubting everything, so as to assess the world from a fresh perspective, clear of any preconceived notions....

The Ethics is a philosophical book written by Baruch Spinoza. It was written in Latin. Although it was published posthumously in 1677, it is his most famous work, and is considered his magnum opus. In The Ethics, Spinoza attempts to demonstrate a fully cohesive philosophical system that strives to provide a coherent picture of reality and to comprehend the meaning of an ethical life. Following a logical step-by-step format, it defines in turn the nature of God, the mind, human bondage to the emotions, and the power of understanding -- moving from a consideration of the eternal, to speculate upon humanity's place in the natural order, freedom, and the path to attainable happiness.(Wikipedia)...

Marcus Aurelius wrote Meditations in Greek while on campaign between 170 and 180, as a source for his own guidance and self-improvement. These memos survive and continue to inspire others to this day. These writings take the form of quotations varying in length from one sentence to long paragraphs. He explicates the Stoic philosophy that the only way a man can be harmed by others is to allow his reaction to overpower him. He shows no particular religious faith in his writings, but seems to believe that some sort of logical, benevolent force organizes the universe in such a way that even bad occurrences happen for the good of the whole.

This short book is part of the Philosophies Ancient and Modern series, which attempts to make Western philosophy more accessible to the general public. In this volume, George Stock provides a concise primer on Stoicism, the ancient philosophy that maintained that the universe is governed entirely by fate, and that humans can achieve happiness only by cultivating a calm acceptance of the vicissitudes of life. Among the Stoics of the Greek and Roman world were its founder, Zeno, the former slave Epictetus, and the Roman emperor Marcus Aurelius. George Stock discusses not only the Stoic ethics, but also less well-known aspects of Stoicism, such as its division of the branches of philosophy, its account of logic, and its natural philosophy.

A Treatise Concerning the Principles of Human Knowledge (Commonly called Treatise when referring to Berkeley's works) is a 1710 work by the Irish Empiricist philosopher George Berkeley. This book largely seeks to refute the claims made by his contemporary John Locke about the nature of human perception. Whilst, like all the Empiricist philosophers, both Locke and Berkeley agreed that there was an outside world, and it was this world which caused the ideas one has within one's mind, Berkeley sought to prove that the outside world was also composed solely of ideas. Berkeley did this by suggesting that Ideas can only resemble Ideas - the mental ideas that we possessed could only resemble other ideas (not physical objects) and thus the external world consisted not of physical form, but rather of ideas. This world was given logic and regularity by some other force, which Berkeley concluded was God....

Categories (Lat. Categoriae, Greek Κατηγορίαι Katēgoriai) is the first of Aristotle's six texts on logic which are collectively known as the Organon. In Categories Aristotle enumerates all the possible kinds of things that can be the subject or the predicate of a proposition. Aristotle places every object of human apprehension under one of ten categories (known to medieval writers as the praedicamenta). Aristotle intended them to enumerate everything that can be expressed without composition or structure, thus anything that can be either the subject or the predicate of a proposition. The ten categories, or classes, are: Substance, Quantity, Quality, Relation, Place, Time, Position, State, Action and Affection.

The Art of Controversy (or The Art of Being Right ) ( Die Kunst, Recht zu Behalten ) is a short treatise written in 1831 by the German philosopher Arthur Schopenhauer in which he presents thirty-eight methods of gaining an unfair advantage in a debate and thereby being right even if you are wrong. Schopenhauer champions the virtue of dialectical argument, in his view wrongly neglected by philosophers in favour of logic, and goes on to discuss the distinction between our conscious intellectual powers and our will. The text is a favourite of debaters including the philosophers AC Grayling and Mary Warnock, and the Mayor of London Boris Johnson. (Summary by Carl Manchester)...

Mary Everest Boole (1832-1916) was born Mary Everest in England and spent her early years in France. She married mathematician George Boole. She was the author of several works on teaching and teaching mathematics in particular. This short book, Philosophy and Fun of Algebra, is meant to be read by children and introduces algebra and logic. She uses the word “algebra” broadly, defining it as a “method of solving problems by honest confession of one’s ignorance”. Using this definition, Boole introduces, in a conversational manner, the concepts of logic and algebra, illustrating these concepts with stories and anecdotes, often from biblical sources. At times, her discussion seems somewhat mystical, speaking of the imagination and angels as messengers which guide one toward the next step in a logical investigation. Boole ends the book with a reminder that algebra’s essential element is “the habitual registration of the exact limits of one’s knowledge” and a call for the public to keep this principle in mind when encountering any situation.

Thomas Troward was a divisional Judge in British-administered India. His avocation was the study of comparative religion. Influences on his thinking, as well as his later writing, included the teachings of Christ, Islam, Hinduism, and Buddhism. After his retirement from the judiciary in 1896, Troward set out to apply logic and a judicial weighing of evidence in the study of matters of cause and effect. The philosopher William James characterized Troward’s Edinburgh Lectures on Mental Science as far and away the ablest statement of philosophy I have met, beautiful in its sustained clearness of thought and style, a really classic statement. According to Alcoholics Anonymous (AA) archivist Nell Wing, early AA members were strongly encouraged to read Thomas Troward's Edinburgh Lectures on Mental Science. In the opening of the 2006 film The Secret , introductory remarks credit Troward's philosophy with inspiring the movie and its production....

The introduction to Hegel's lectures on the philosophy of world history is often used to introduce students to Hegel's philosophy, in part because Hegel's sometimes difficult style is muted in the lectures, and he discourses on accessible themes such as world events in order to explain his philosophy. Much of the work is spent defining and characterizing Geist or spirit. Geist is similar to the culture of people, and is constantly reworking itself to keep up with the changes of society, while at the same time working to produce those changes through what Hegel called the cunning of reason. Another important theme of the text is the focus on world history, rather than regional or state history. The obscure writings of Jakob Böhme had a strong effect on Hegel. Böhme had written that the Fall of Man was a necessary stage in the evolution of the universe. This evolution was, itself, the result of God's desire for complete self-awareness. Hegel was fascinated by the works of Spinoza, Kant, Rousseau, and Goethe, and by the French Revolution. Modern philosophy, culture, and society seemed to Hegel fraught with contradictions and tensions, ...
