" ...Young fit choix de la carrière de la médecine, dans laquelle il espérait trouver la fortune et l'indépendance. Ses études médicales commencèrent à Londres sous Baillie et Cruickshank; il les continua à Édimbourg, où brillaient alors les docteurs Black, Munro et Gregory; mais ce fut seulement à Goettingue que, dans l'année suivante (1795), il prit son grade de docteur. Avant de se soumettre à cette formalité si vaine, et, toutefois, si impérieusement exigée, Young, à peine sorti de l'adolescence, s'était déjà révélé au monde scientifique par une note relative à la gomme Ladanum; par la polémique qu'il avait soutenue contre le docteur Beddoës au sujet de la théorie de Crawford sur le calorique; par un mémoire concernant les habitudes des araignées et le système de Fabricius, le tout enrichi de recherches d'érudition; enfin, par un travail sur lequel j'insisterai davantage à cause de son grand mérite, de la faveur inusitée dont il fut l'objet en naissant, et de l'oubli dans lequel on l'a laissé depuis..."

" ...Lorsque Fresnel publia pour la première fois ce fait inattendu, il ne l'avait encore vérifié qu'à l'aide d'une méthode indirecte, remarquable par l'étrange circonstance que la réfraction des rayons se déduit d'expériences dans lesquelles aucune réfraction ne s'est opérée. Aussi notre confrère trouva-t-il plus d'un incrédule. La singularité de la découverte commandait peut-être quelque réserve; peut-être aussi, aux yeux de diverses personnes, avait-elle, comme l'ancienne loi d'Huygens, le tort d'être le fruit d'une hypothèse ! Quoi qu'il en soit, Fresnel aborda la difficulté de front. En montrant dans un parallélépipède de topaze formé de deux prismes de même angle adossés, qu'aucun rayon ne passait entre deux faces opposées et parallèles sans être dévié, il rendit toute objection inutile..."

" Je n'ai pas la sotte vanité de m'imaginer que quelqu'un, dans un avenir même peu éloigné, aura la curiosité de rechercher comment ma première éducation s'est faite, comment mon intelligence s'est développée; mais des biographes improvisés et sans mission, ayant donné à ce sujet des détails complètement inexacts, et qui impliqueraient la négligence de mes parents, je me crois obligé de les rectifier..."

...Condorcet n'a pas été un académicien ordinaire, voué aux seuls travaux de cabinet; un philosophe spéculatif, un citoyen sans entrailles; les coteries littéraires, économiques, politiques, se sont emparées depuis longtemps de sa vie, de ses actes publics et privés, de ses ouvrages. Personne n'a eu plus à souffrir de la légèreté, de la jalousie et du fanatisme, ces trois redoutables fléaux des réputations. En traçant un portrait que je me suis efforcé de rendre ressemblant, je ne pouvais avoir la prétention d'être cru sur parole. Si pour chaque trait caractéristique je m'étais borné à réunir, à conserver soigneusement pour moi seul, tout ce qui établissait la vérité de mes impressions, je n'aurais pas fait assez: il fallait mettre le public à même de prononcer en connaissance de cause entre la plupart de mes prédécesseurs et moi; il fallait donc combattre, visière levée, les vues fausses, mensongères, passionnées de ceux qui, d'après ma conviction intime, n'ont rien saisi de vrai et d'exact dans la grande, dans la majestueuse figure de Condorcet...
