At the heart of the novel is Dr. Pascal Rougon, a scientist and doctor who has dedicated himself to researching the laws of heredity. He is a dazzling figure who stands for the rationalist and scientific view of the world that Zola, as a representative of naturalism, repeatedly emphasizes in his works. Pascal is a passionate advocate of science and firmly believes that progress can improve human life through research into the laws of nature. He devotes his entire life to studying the genetic and psychological predispositions of his family in order to understand and document the destructive tendencies he observes in the members of the Rougon-Macquart line.

The novel shows the tension between Pascal's scientific curiosity and the emotional reality of his personal life. Pascal lives with his niece Clotilde, who becomes his pupil and later his lover. This relationship represents a conflict between Pascal's rational, scientific view of the world and his passionate, human emotions. Clotilde, who is deeply religious and superstitious at the beginning of the novel, stands in contrast to Pascal and represents the influence of tradition, religion and conservatism. However, as the story progresses, a deeper connection develops between the two, taking Pascal's belief in science to a new, human level.

A central theme of the novel is the problem of heredity and degeneration. In his studies, Pascal has documented the genetic burdens of his family, which manifest themselves in mental illness, addiction and violent tendencies. Zola uses the Rougon-Macquart family as a microcosm to examine the power of the laws of heredity and to show how strongly biological nature shapes people. Pascal is aware of the dark side of his family, but he remains optimistic and believes in the possibility of progress and healing through science.

However, in "Doctor Pascal", Zola goes beyond the mere depiction of science and reflects on the limits of knowledge and the value of emotions. Although Pascal wants to continue his studies, he is hindered by his mother Félicité, who tries to destroy his notes in order to hide the family's dark secrets. This confrontation symbolizes the struggle between the forces of progress and reason on the one hand and the traditional, repressive powers on the other. Félicité represents the desire to control the past and hide the unpleasant truths that science might reveal.

At the end of the novel, Pascal's faith in science is challenged by the reality of human mortality. Pascal's sudden death leaves Clotilde in a difficult position, and she eventually decides to carry on the knowledge she inherited from him by giving birth to a son, symbolic of the hope for a better future. This birth represents a reconciliation between Pascal's rationalism and Clotilde's emotional and spiritual awakening and provides an optimistic ending for the novel and the entire "Rougon-Macquart" series.

Money does not play a central role in "Doctor Pascal", as it does in other novels by Émile Zola, such as "Money" ("L'Argent"), but it is nevertheless an important theme that influences the characters' conflicts and relationships. The theme of money comes to the fore particularly with regard to the Rougon-Macquart family and the conservative forces embodied by Pascal's mother Félicité.

Félicité is a woman who is strongly obsessed with material values and the preservation of family power and prestige. She represents the conservative side of the family, who do everything they can to protect their wealth and social status. In contrast to Pascal, who is dedicated to science and the truth, Félicité endeavors to sabotage her son's hereditary research because she fears that documenting the dark secrets and aberrations within the family could damage the reputation and thus also the financial interests of the Rougon family. This juxtaposition shows how strongly material interests influence the family's actions.
