{{blockquote|In putting an end to the long, diverse and fruitful activity of Gustave Le Bon, death deprived our culture of a truly remarkable man. His was a man of most exceptional intelligence; it sprang entirely from within himself; he was his own master, his own initiator.... Science and philosophy have suffered a cruel loss.<ref>{{cite news|author=Staff writer(s)|title=Gustave Le Bon obituary|publisher=Journal des débats|date=14 December 1931}}</ref>}}
