"Plain Facts for Old and Young" by John Harvey Kellogg is a scientific publication written in the late 19th century. The book addresses vital issues related to human sexuality, reproduction, and the physical differences between sexes, with the intent to educate readers on these often-taboo subjects. It aims to counteract widespread ignorance and discuss the implications of sexual behavior and health on individuals and society as a whole. The opening of the work introduces the motivations behind its creation, emphasizing the pressing need for accurate information on sexual matters, recognizing both the ignorance surrounding them and the potential dangers of misinformation. Kellogg outlines his objectives to present facts in a straightforward manner, avoiding the sensational or moralistic tones often associated with similar publications. The text suggests a structured approach, beginning with a biological overview of sexual reproduction in both plants and animals before delving into specific functions and anatomy related to human sexuality, setting the foundation for deeper discussions on sexual health, education, and morality that follow in later chapters.
