Shelley makes full use of themes that were popular during the time she wrote Frankenstein. She is concerned with the use of knowledge for good or evil purposes, the invasion of technology into modern life, the treatment of the poor or uneducated, and the restorative powers of nature in the face of unnatural events. She addresses each concern in the novel, but some concerns are not fully addressed or answered. For instance, how much learning can man obtain without jeopardizing himself or others? This is a question that has no clear answer in the novel.
Victor Frankenstein learns all he can about the field of science, both before, during, and after his work at the university. Prior to his enrollment at the university, Victor focuses on the ancient art of alchemy, which had been discredited by the time of Shelley's writing. Alchemy was an early form of chemistry, with philosophic and magical associations, studied in the Middle Ages. Its chief aims were to change base metals into gold and to discover the elixir of perpetual youth. At the university, Victor gains new knowledge with the most modern science as a background. However, it is Victor's combination of old and new science that leads him down a path to self-destruction. This is one of Shelley's themes:"How can we harness the knowledge that we have so that it is not self destructive and for the benefit of all mankind?" The answer is not an easy one, and Shelley is not clear on her feelings about the use or abuse of technology. The reanimation of man from the dead is a useful thing to revive people who have died too soon, but what responsibility must we exercise once we bring people back from the dead? This is a morally perplexing question. Thus, we are stuck in a dilemma:"How far can we go in raising the dead without destroying the living?" Shelley seems to conclude that man cannot handle becoming both like God and a creator without much difficulty.
