Letters to his brother.
"I am not sulking; far from it...I have no lack of ink and paper; I am too careful of them to lack them; but I do lack time...So you still think I am sulking because I do not reply! But imagine, my dear and petulant brother, that for several weeks I have been pursuing, with unequalled persistence, some abominable conic problems proposed at the fellowship examination, and once I have mounted my hobby-horse, good-bye to letters, good-bye to replies, goodbye to everything." (Carpentras, 27th November, 1848.)
"You are right, seven times right to storm at me, to grumble at my silence, and I admit, in all contrition, that I am the worst correspondent you could find. To force myself to write a letter is to place myself on the rack, as well you know...But why do you get it into your head, why do you tell me, that I disdain you, that I forget you, that I ignore you, you, my best friend?...For my silence blame only the multiplicity of tasks, which often surpasses, not my courage, but my strength and my time." (Ajaccio, 1st June, 1851.)
