Parerga And Paralipomena
''Parerga and Paralipomena'' (Greek for "Appendices" and "Omissions", respectively; ) is a collection of philosophical reflections by Arthur Schopenhauer published in 1851. The selection was compiled not as a summation of or introduction to Schopenhauer's philosophy, but as augmentary readings for those who had already embraced it, although the author maintained it would be comprehensible and of interest to the uninitiated nevertheless. The collection is divided into two volumes, covering first the ''parerga'' and thereafter the ''paralipomena'' to that philosophy. The ''parerga'' are six extended essays intended as supplementary to the author's thought. The ''paralipomena'', shorter elaborations divided by topic into thirty-one subheadings, cover material hitherto unaddressed by the philosopher but deemed by him to be complementary to the ''parerga''. Contents Volume One (''Parerga'') * Preface * Sketch of a History of the Doctrine of the Ideal and the Real * Fragments for th ...

Diatonic Scale
In music theory a diatonic scale is a heptatonic scale, heptatonic (seven-note) scale that includes five whole steps (whole tones) and two half steps (semitones) in each octave, in which the two half steps are separated from each other by either two or three whole steps. In other words, the half steps are maximally separated from each other. The seven pitch (music), pitches of any diatonic scale can also be obtained by using a Interval cycle, chain of six perfect fifths. For instance, the seven natural (music), natural pitch classes that form the C-major scale can be obtained from a stack of perfect fifths starting from F: :F–C–G–D–A–E–B. Any sequence of seven successive natural notes, such as C–D–E–F–G–A–B, and any Transposition (music), transposition thereof, is a diatonic scale. Modern musical keyboards are designed so that the white-key notes form a diatonic scale, though transpositions of this diatonic scale require one or more black keys. A diaton ...

Through the Renaissance music, Renaissance (and much later in some shapenote publications) various interlocking four-, five- and six-note systems were employed to cover the octave. The tonic sol-fa method popularized the seven syllables commonly used in English-speaking countries: ''do'' (spelled ''doh'' in tonic sol-fa),''Oxford English Dictionary'' 2nd Ed.

Johannes Itten
Johannes Itten (11 November 1888 – 25 March 1967) was a Swiss expressionist painter, designer, teacher, writer and theorist associated with the Bauhaus (''Staatliches Bauhaus'') school. Together with German-American painter Lyonel Feininger and German sculptor Gerhard Marcks, under the direction of German architect Walter Gropius, Itten was part of the core of the Weimar Bauhaus. Life and work He was born in Südern-Linden, Switzerland. From 1904 to 1908 he trained as an elementary school teacher.

In 1909 he enrolled at the École des Beaux-Arts in Geneva but was unimpressed with the educators there, and returned to Bern. Itten's studies at the Bern-Hofwil Teachers' Academy with Ernst Schneider proved seminal for his later work as a master at the Bauhaus. Itten adopted principles espoused by Schneider, includ ...

Strabismus
Strabismus is an eye disorder in which the eyes do not properly align with each other when looking at an object. The eye that is pointed at an object can alternate. The condition may be present occasionally or constantly. If present during a large part of childhood, it may result in amblyopia, or lazy eyes, and loss of depth perception. If onset is during adulthood, it is more likely to result in diplopia, double vision. Strabismus can occur out of muscle dysfunction (e.g., myasthenia gravis), farsightedness, problems in the brain, trauma, or infections. Risk factors include premature birth, cerebral palsy, and a family history of the condition. Types include esotropia, where the eyes are crossed ("cross eyed"); exotropia, where the eyes diverge ("lazy eyed" or "wall eyed"); and hypertropia or hypotropia, where they are vertically misaligned. They can also be classified by whether the problem is present in all directions a person looks (comitant) or varies by direction (inco ...

Sextus Empiricus
Sextus Empiricus (, ; ) was a Greek Pyrrhonist philosopher and Empiric school physician with Roman citizenship. His philosophical works are the most complete surviving account of ancient Greek and Roman Pyrrhonism, and because of the arguments they contain against the other Hellenistic philosophies, they are also a major source of information about those philosophies. Life Little is known about Sextus Empiricus. He likely lived in Alexandria, Rome, or Athens. His Roman name, Sextus, implies he was a Roman citizen. The ''Suda,'' a 10th-century Byzantine encyclopedia, states that he was the same person as Sextus of Chaeronea,Suda, Sextos σ 235. as do other pre-modern sources, but this identification is commonly doubted. In his medical work, as reflected by his name, tradition maintains that he belonged to the Empiric school in which Pyrrhonism was popular. However, at least twice in his writings, Sextus seems to place himself closer to the Methodic school. Philosophy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
An Essay Concerning Human Understanding
''An Essay Concerning Human Understanding'' is a work by John Locke concerning the foundation of human knowledge and understanding. It first appeared in 1689 (although dated 1690) with the printed title ''An Essay Concerning Humane Understanding''. He describes the mind at birth as a blank slate ('' tabula rasa'', although he did not use those actual words) filled later through experience. The essay was one of the principal sources of empiricism in modern philosophy, and influenced many enlightenment philosophers, such as David Hume and George Berkeley. Book I of the ''Essay'' is Locke's attempt to refute the rationalist notion of innate ideas. Book II sets out Locke's theory of ideas, including his distinction between passively acquired ''simple ideas''—such as "red", "sweet", "round"—and actively built ''complex ideas'', such as numbers, causes and effects, abstract ideas, ideas of substances, identity, and diversity. Locke also distinguishes between the truly existing ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
John Locke
John Locke (; 29 August 1632 (Old Style and New Style dates, O.S.) – 28 October 1704 (Old Style and New Style dates, O.S.)) was an English philosopher and physician, widely regarded as one of the most influential of the Enlightenment thinkers and commonly known as the "father of liberalism". Considered one of the first of the British empiricists, following the tradition of Francis Bacon, Locke is equally important to social contract theory. His work greatly affected the development of epistemology and political philosophy. His writings influenced Voltaire and Jean-Jacques Rousseau, and many Scottish Enlightenment thinkers, as well as the American Revolutionaries. His contributions to classical republicanism and liberal theory are reflected in the United States Declaration of Independence. Internationally, Locke's political-legal principles continue to have a profound influence on the theory and practice of limited representative government and the protection of basic right ...

Discourse On The Method
''Discourse on the Method of Rightly Conducting One's Reason and of Seeking Truth in the Sciences'' () is a philosophical and autobiographical treatise published by René Descartes in 1637. It is best known as the source of the famous quotation ''"Je pense, donc je suis"'' (" I think, therefore I am", or "I am thinking, therefore I exist"), which occurs in Part IV of the work. A similar argument, without this precise wording, is found in '' Meditations on First Philosophy'' (1641), and a Latin version of the same statement '' Cogito, ergo sum'' is found in '' Principles of Philosophy'' (1644). ''Discourse on the Method'' is one of the most influential works in the history of modern philosophy, and important to the development of natural sciences. In this work, Descartes tackles the problem of skepticism, which had previously been studied by other philosophers. While addressing some of his predecessors and contemporaries, Descartes modified their approach to account for a truth ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
