Quote 13
"Communication is health; communication is happiness, communication –" he muttered. (4.99)
One of Septimus' most important messages is about communication. He believes birds are talking to him in Greek, and he just wishes he could find the right words to express how he feels. Finally his death becomes the only available form of communication – and Clarissa senses that.
Quote 14
And there the motor car stood, with drawn blinds, and upon them a curious pattern like a tree, Septimus thought, and this gradual drawing together of everything to one centre before his eyes, as if some horror had come almost to the surface and was about to burst into flames, terrified him. (1.33)
Even when looking at something as ordinary as a motor car, Septimus can become terrified. Everyday life is now just as frightening as his memories of war.
Quote 15
So, thought Septimus, looking up, they are signalling to me. Not indeed in actual words; that is, he could not read the language yet; but it was plain enough, this beauty, this exquisite beauty, and tears filled his eyes as he looked at the smoke words languishing and melting in the sky […]. (1.60)
Part of Septimus’ madness is striving for communication. He thinks birds and airplanes are trying to tell him something, and in the end, he attempts to communicate through his suicide.
