Inevitability of Genetic Modification in Redesigning Humans

Technological advancement drives human society to change as it itself expands through research into the unknown. Often, new ideas exhibit a threat to the ancient fundamentals of society, leading to a protest of many remarkable innovations. In the study of biology, theorists have begun to propose change at a microscopic level, which will have a profound effect on society: genetically modifying the human species. Gregory Stock addresses the future of this concept in his book, Redesigning Humans. Using metaphor to enhance the journey into the future, substance to present the immense possibilities biological modification will introduce, and appeal to pathos to create fear and excitement, Stock argues that the rebirth of humanity is certain and the world should accept the change.

Stock uses metaphor to emphasize the inevitability of the genetic future and to show how crucial genome modification is for the future of society. He addresses worries that once humans begin altering their natures, the modifications made will progress negatively, harming society. Metaphor reinforces the rebuttal of this claim when Stock says, “advanced reproductive technologies are more like a slippery sidewalk than a slippery slope. Rather than sliding uncontrollably into some deep abyss, we more likely will take a spill or two, get up, brush ourselves off, and continue cautiously on our way” (Stock 151). The comparison to a sidewalk clarifies that every movement will be by choice because of the implication of walking opposed to falling down a “slippery slope”. This refutes the claim that the technology will harm society, but does not remove the idea of inevitability due to the inclusion of “slippery”. On account of limited metaphorical language us...

...ience excited for the future of society. By appealing to pathos to create excitement for the progression of society and fear of genetic diseases that are eliminable, Stock encourages the reader to embrace genetic modification.

Metaphor, appeal to substance, and appeal to pathos assist in Stock’s portrayal of germline engineering as a certain and constructive technology in Redesigning Humans. Metaphor accentuates the inevitability and makes the audience understand the point the author makes. Substance reinforces this idea through hypothetical examples, which enable the reader to comprehend the importance of genetic modification, and appeal to pathos, which helps create a desire for this future. Individuals will continue to strive for the intangible on a quest to perfect the human condition, and germline engineering serves as a vital leap forward in this crusade.
