The longing for aerial flight has been one of mankind's most consuming preoccupations. A burning desire for lightness, verticality, and flight is opposed to the fatality of universal gravity. Jules Michelet, in his study of the subject, entitled L'Oiseau (The Bird), which he wrote toward the end of his life, deems this aspiration for upward motion to be characteristic of all nature. He writes: “It is the cry of all the earth, of the world and of all life… : ‘Wings! (...) We want wings, we want flight and movement.’” From ancient times, this basic element of physical experience has nourished human imagination and been a source of motivation for the pursuit of scientific knowledge. Mesopotamian civilization had its winged divinities and spirits; indeed the Western tradition of depicting winged persons has been linked to the influence of Mesopotamian art. As Jules Duhem has pointed out, four centuries before Jesus Christ, Aristotle himself was already exploring certain notions that have become part of the history of ideas of aeronautics and astronomy. Among these are the ideas of void, weight, the resistance of air, and the movement of birds and other flying creatures. Duhem has also demonstrated that Aristotle proposed an explanation, as imperfect as it was, for what causes projectiles to fall from the sky. Throughout the ages, humanity has continually expressed its desire to fly: “Man is proud of being free and of leaning on nothing,” Elias Canetti has written in regard to man's upright position. Striking examples of the impulse to fly are to be found not only in scientific discourse but in myths, literature, and works of art. (shrink)

Scientific study of dreams requires the most objective methods to reliably analyze dream content. In this context, artificial intelligence should prove useful for an automatic and non subjective scoring technique. Past research has utilized word search and emotional affiliation methods, to model and automatically match human judges’ scoring of dream report’s negative emotional tone. The current study added word associations to improve the model’s accuracy. Word associations were established using words’ frequency of co-occurrence with their defining words as found in (...) a dictionary and an encyclopedia. It was hypothesized that this addition would facilitate the machine learning model and improve its predictability beyond those of previous models. With a sample of 458 dreams, this model demonstrated an improvement in accuracy from 59% to 63% on the negative emotional tone scale, and for the first time reached an accuracy of 77% on the positive scale.

Thomas De Koninck | : Loin de s’opposer, la dignité de la personne et la primauté du bien commun s’impliquent au contraire l’une l’autre réciproquement. C’est ce qu’on tente principalement de montrer dans le présent article. | : Far from being opposed one to the other, the dignity of the person and the primacy of the common good do in fact imply one another reciprocally. This is chiefly what the present article attempts to bring out.

Résumé On tente ici de montrer à quel point la question de Dieu s’avère plus clairement que jamais la question par excellence, et de résumer les pistes de réflexion que suggèrent à cet égard les apports les plus remarquables du savoir et des arts aujourd’hui, mais aussi de l’expérience humaine et de la pensée philosophique, tout en marquant leurs liens avec la pensée classique sur ce sujet urgent entre tous.We try here to show how and why it is that the (...) question of God should have become more clearly than ever the question among questions, and to bring out the most remarkable contributions, in that regard, of contemporary science and the arts, as well as of common human experience and philosophical thought, while underscoring their links with classical thought on this most urgent of matters.
