“One phenomenon is certain and I can vouch for its absolute certainty: the sudden and immediate appearance of a solution at the very moment of sudden awakening. On being very abruptly awakened by an external noise, a solution long searched for appeared to me at once without the slightest instant of reflection on my part-the fact was remarkable enough to have struck me unforgettably-and in a quite different direction from any of those which I had previously tried to follow.”
Jacques Hadamard

“Οι ιστορικοί που μελέτησαν την εντυπωσιακή ζωή του Évariste Galois μας αποκάλυψαν ότι, σύμφωνα με τη μαρτυρία ενός συμμαθητή του, από την εποχή του γυμνασίου ακόμη απεχθανόταν την ανάγνωση πραγματειών άλγεβρας, διότι δε μπορούσε να εντοπίσει σ' αυτές τα χαρακτηριστικά γνωρίσματα των επινοητών. Ο Drach, λοιπόν, η εργασία του οποίου εξάλλου σχετίζεται στενά με εκείνη του Galois, ακολουθεί τον ίδιο τρόπο προσέγγισης. Επιθυμεί πάντοτε να ανατρέχει ακριβώς στη μορφή με την οποία οι ανακαλύψεις παρουσιάστηκαν στους συγγραφείς τους. Αντίθετα, οι περισσότεροι μαθηματικοί που απάντησαν στην έρευνα των Claparède και Flournoy, όταν μελετούν οποιαδήποτε προγενέστερη εργασία, προτιμούν να την αναλύουν και να την επανανακαλύπτουν μόνοι τους. Αυτή είναι και η δική μου προσέγγιση, έτσι ώστε τελικά γνωρίζω σε κάθε περίπτωση μόνο έναν επινοητή, τον εαυτό μου.”
Jacques Hadamard, The Psychology of Invention in the Mathematical Field

“The object of mathematical rigor is to sanction and legitimize the conquests of intuition, and there was never any other object for it.”
Jacques Hadamard
