Despite his flaws, Jason is the most adaptable of the Compson men, able as he is to hold a job and support his family financially without resorting to suicide or alcoholism. One way to account for his success is to note the high degree of control he has over his own thoughts–a high degree at least when compared to that his brothers.
Jason’s thoughts are usually closely tied to speech. Frequently in his section, Jason’s thoughts return to real or imagined conversations, especially conversations with his mother. Often his thoughts are so fully speech-like that he is capable being witty in his own internal monologue: “She [Dilsey] was so old she couldn’t do any more than move hardly. But that’s all right: we need somebody in the kitchen to eat up the grub the young ones cant tote off.” (185) He frequently repeats to himself judgments and witticisms that he has apparently made in the past, as on p. 227: “You take a little two by four country storekeeper like I say it takes a man with just five hundred dollars to worry about it fifty thousand dollars’ worth.” (Emphasis mine.) An electronic search of the text reveals the string “like I say” occurs no fewer than 26 times in Jason’s section. He repeats these worn-down scraps of speech like mantras throughout the day. Jason makes these constant efforts to order his thoughts as rational, comprehensible speech, in order to keep them under conscious control, to shield himself from other unwanted thoughts–in particular, his repressed sexual desires.
It is not what Jason speaks to himself but rather what he refuses to speak that illustrates this repressed content most fully. Jason often dwells on resentment towards his sister’s sexual exploits, and yet the name “Caddy” occurs only three times in Jason’s section. (In contrast “Ben”/”Benjamin” appears 23 times, and “Quentin” 48.) While Benjy can’t hear the name “Caddy” without bellowing, Jason can barely bring himself to think the name. When recalling his father’s funeral Jason notices that he was experiencing emotion, and yet he refuses to name this feeling, whether it is grief, or a murderous Oedipal rage: “We stood there, looking at the grave, and then I got to thinking about when we were little and one thing and another and I got to feeling funny again, kind of mad or something.” (203) Perhaps Jason unconsciously believes that if he names the experience, even in his internal monologue, he thereby grants it existence.
In the last paragraph of his section, when Jason’s thoughts turn toward Benjy’s castration, he likewise avoids descriptive terms like “penis” and “castration,” but rather alludes to the act indirectly. At one point he thinks, “Well, like I say they never started soon enough with their cutting, and they quit too quick. I know at least two more that needed something like that, and one of them not over a mile away, either.” (263) The ambiguity of the passage perhaps reveals an unconscious wish that he himself be castrated, to be free from his unspeakable desires, in the same state that he imagines Benjy to be, with desires that “he couldn’t even remember . . . and couldn’t want any longer.” (253)
It is difficult to imagine either of the other Compson brothers deliberately avoiding the act of thinking about something. Certainly not Benjy! Quentin’s thoughts frequently turn to taboo subjects that Jason avoids, like incest and abortion, which he is unwilling or, more likely, unable to repress. Moreover, he is frequently swept away by his own thoughts–once to the extent that he attacks Gerald Bland without realizing it or remembering it. In comparison, Jason’s repressive tactics can be seen as positive and adaptive; and in a time and place devoid of psychotherapy, yoga, and mediation retreats, what options does Jason have besides repression?
