Oedipus complex
Perhaps Sigmund Freud's most celebrated theory of sexuality, the Oedipus complex takes its name from the title character of the Greek play Oedipus Rex. In the story, Oedipus is prophesied to murder his father and have sex with his mother (and he does, though unwittingly). Freud argued that these repressed desires are present in most young boys. (The female version is called the Electra complex.)
D.H. Lawrence was aware of Freud's theory, and Sons and Lovers famously uses the Oedipus complex as its base for exploring Paul's relationship with his mother. Paul is hopelessly devoted to his mother, and that love often borders on romantic desire. Lawrence writes many scenes between the two that go beyond the bounds of conventional mother-son love. Completing the Oedipal equation, Paul murderously hates his father and often fantasizes about his death.
Paul assuages his guilty, incestuous feelings by transferring them elsewhere, and the greatest receivers are Miriam and Clara (note that transference is another Freudian term). However, Paul cannot love either woman nearly as much as he does his mother, though he does not always realize that this is an impediment to his romantic life. The older, independent Clara, especially, is a failed maternal substitute for Paul. In this setup, Baxter Dawes can be seen as an imposing father figure; his savage beating of Paul, then, can be viewed as Paul's unconsciously desired punishment for his guilt. Paul's eagerness to befriend Dawes once he is ill (which makes him something like the murdered father) further reveals his guilt over the situation.
But Lawrence adds a twist to the Oedipus complex: Mrs. Morel is saddled with it as well. She desires both William and Paul in near-romantic ways, and she despises all their girlfriends. She, too, engages in transference, projecting her dissatisfaction with her marriage onto her smothering love for her sons. At the end of the novel, Paul takes a major step in releasing himself from his Oedipus complex. He intentionally overdoses his dying mother with morphia, an act that reduces her suffering but also subverts his Oedipal fate, since he does not kill his father, but his mother.
Bondage
Lawrence discusses bondage, or servitude, in two major ways: social and romantic. Socially, Mrs. Morel feels bound by her status as a woman and by industrialism. She complains of feeling "'buried alive,'" a logical lament for someone married to a miner, and even the children feel they are in a "tight place of anxiety." Though she joins a women's group, she must remain a housewife for life, and thus is jealous of Miriam, who is able to utilize her intellect in more opportunities. Ironically, Paul feels free in his job at the factory, enjoying the work and the company of the working-class women, though one gets the sense that he would still rather be painting.
Romantic bondage is given far more emphasis in the novel. Paul (and William, to a somewhat lesser extent) feels bound to his mother, and cannot imagine ever abandoning her or even marrying anyone else. He is preoccupied with the notion of lovers "belonging" to each other, and his true desire, revealed at the end, is for a woman to claim him forcefully as her own. He feels the sacrificial Miriam fails in this regard and that Clara always belonged to Baxter Dawes. It is clear that no woman could ever match the intensity and steadfastness of his mother's claim.
Complementing the theme of bondage is the novel's treatment of jealousy. Mrs. Morel is constantly jealous of her sons' lovers, and she masks this jealousy very thinly. Morel, too, is jealous over his wife's closer relationships with his sons and over their successes. Paul frequently rouses jealousy in Miriam with his flirtations with Agatha Leiver and Beatrice, and Dawes is violently jealous of Paul's romance with Clara.
Contradictions and oppositions
Lawrence demonstrates how contradictions emerge so easily in human nature, especially with love and hate. Paul vacillates between hatred and love for all the women in his life, including his mother at times. Often he loves and hates at the same time, especially with Miriam. Mrs. Morel, too, has some reserve of love for her husband even when she hates him, although this love dissipates over time.
Lawrence also uses the opposition of the body and mind to expose the contradictory nature of desire; frequently, characters pair up with someone who is quite unlike them. Mrs. Morel initially likes the hearty, vigorous Morel because he is so far removed from her dainty, refined, intellectual nature. Paul's attraction to Miriam, his spiritual soul mate, is less intense than his desire for the sensual, physical Clara.
The decay of the body also influences the spiritual relationships. When Mrs. Morel dies, Morel grows more sensitive, though he still refuses to look at her body. Dawes's illness, too, removes his threat to Paul, who befriends his ailing rival.
Nature and flowers
Sons and Lovers has a great deal of description of the natural environment. Often, the weather and environment reflect the characters' emotions through the literary technique of pathetic fallacy. The description is frequently eroticized, both to indicate sexual energy and to slip pass the censors in Lawrence's repressive time.
Lawrence's characters also experience moments of transcendence while alone in nature, much as the Romantics did. More frequently, characters bond deeply while in nature. Lawrence uses flowers throughout the novel to symbolize these deep connections. However, flowers are sometimes agents of division, as when Paul is repulsed by Miriam's fawning behavior towards the daffodil.
