"Herakleitos... explained the world by man rather than man by the world. ...Aristotle implies that soul is identical with the dry exhalation, and this is ...confirmed by the fragments. Man is made... of... fire, water, and earth. But, just as in the macrocosm fire is... the one wisdom, so in the microcosm... fire alone is conscious. When it has left the body..., the mere earth and water, is... worthless (fr. 85)."
Heraclitus was an ancient Greek pre-Socratic philosopher from the city of Ephesus, which was then part of the Persian Empire. He exerts a wide influence on Western philosophy, both ancient and modern, through the works of such authors as Plato, Aristotle, the Stoics, Georg Wilhelm Friedrich Hegel, Friedrich Nietzsche, and Martin Heidegger.
"I cannot approve of Heraclitus, who, being self-taught and arrogant, said, "I have explored myself." Nor can I praise him for hiding his poem in the temple of Artemis, in order that it might be published afterwards as a mystery; and those who take an interest in such things say that Euripides the tragic poet came there and read it, and, gradually learning it by heart, carefully handed down to posterity this darkness of Heraclitus."
"Herakleitos, about 460 B.C., one of the boldest thinkers of ancient Greece, declared that Homer deserved to be ejected from public assemblies and flogged..."
"When... Heraclitus names the world an ever-living fire that... extinguishes itself and again kindles itself, when... all is exchanged for fire and fire for all... he can only understand by this that fire, this restless, all-consuming, all-transmuting, and equally (in heat) all-vivifying element, represents the constant force of this eternal alteration and transformation, the notion of life, in the most vivid and energetic manner. ...the means of which the power of motion that is precedent to all matter avails itself for the production of the living process of things. Heraclitus... explains the multiplicity of things... [fire] condenses itself into material elements, first air, then water, then earth. ...These two processes of extinction and ignition... alternate... in perpetual rotation with each other and... in stated periods the world resolves itself into the primal fire, in order to re-create itself out of it again. ...[F]ire is to him... the principle of movement, of physical as of spiritual vitality; the soul itself is a fiery vapour; its power and perfection depend on its being pure from all grosser and duller elements."
"In... Heraclitus... Becoming occupies the foremost place. He regarded that which moves, the fire, as the basic element. The difficulty, to reconcile the... one fundamental principle with the infinite variety of phenomena, is solved... by recognizing... strife of... opposites is... a kind of harmony. ...[T]he world is ...one and many ..."the opposite tension" of ...opposites ...constitutes the unity of the One. He says: "...war is common to all and strife is justice ...all things come into being and pass away through strife." ...[T]hat infinite and eternal undifferentiated Being ...cannot ...explain the infinite variety of things. This leads to the antithesis of Being and Becoming and ...to the solution of Heraclitus ...change ...is the fundamental principle; the "imperishable change, that renovates the world," as the poets have called it. But ...change ...is not a material cause and therefore is represented ...by the fire ...both matter and a moving force. ...[[Physics|[P]hysics]] is ...extremely near to ...Heraclitus ...[i]f we replace ..."fire" by ..."energy" ...Energy is a substance, since its total ...does not change, and ...elementary particles can ...be made from this ...Energy may be called the fundamental cause for all change in the world. ...Energy is ...that which moves; it may be called the primary cause of all change, and ...can be transformed into matter or heat or light. The strife between opposites in the philosophy of Heraclitus can be found in the strife between two different forms of energy."
"If the flow is steady, the field velocity vectors and the system of streamlines remain unaffected by the progress of time. Looking at the vector field and its streamlines we do not notice any change. Yet if we could distinguish the different particles of fluid from each other, we could observe incessant change... We have here two aspects of a steady flow, one of unchanging persistence, the other of incessant change. ...Heraclitus was called the "Dark Philosopher"; his views of human affairs were sombre and his sayings obscure. ... "You cannot look twice at the same river; for fresh waters are ever flowing in." "We look and do not look at the same rivers; we are, and we are not." What is the intended meaning of these sentences? I do not venture to find out. Yet I think that the originator of these senteces came pretty close to formulating the concept "steady flow of a fluid."
"The true Herakleitean doctrine doubtless was, that sleep was produced by the encroachment of moist, dark exhalations from the water in the body, which cause the fire to, burn low. In sleep, we lose contact with the fire in the world which is common to all, and retire to a world of our own (fr. 95). In a soul where the fire and water are evenly balanced, the equilibrium is restored in the morning by an equal advance of the bright exhalation."
"The wound is the place where the Light enters you."
Rumi"Be the change that you wish to see in the world."
Mahatma Gandhi"In philosophy equally as in poetry it is the highest and most useful prerogative of genius to produce the strongest impressions of novelty, while it rescues admitted truths from the neglect caused by the very circumstance of their universal admission."
Samuel Taylor Coleridge"An [hypertext] encyclopaedia will be an overall attempt by the knowledgeable, the learned societies or anyone else, to represent the state-of-the-art in their field. An encyclopaedia will be a living document, as up to date as it can be, instantly accessible at any time. It will contain carefully authored explanations and summaries of the subject, as well as computer-generated indexes of literature. A reference to a paper from the encyclopaedia conveys authority and acceptance by academic society. A measure of a paper’s standing may be conveyed by the number of links it is away from an encyclopaedia."
Tim Berners-Lee"The British intellectual tradition is empirical and liberal, the French is rationalist and aristocratic, and the German is idealist and conservative. ...In the great ontological debate between mind and matter, German philosophy comes down solidly on the side of mind. Its emphasis is intuition as opposed to reason, ideas as opposed to facts."
"To know the mighty works of God, to comprehend His wisdom and majesty and power; to appreciate, in degree, the wonderful workings of His laws, surely all this must be a pleasing and acceptable mode of worship to the Most High, to whom ignorance cannot be more grateful than knowledge."
