In this searching philosophical work, science and art are not decorative pursuits but essential measures of what it means to be human. Framed as a serious essay or treatise from What to Do?, it questions recurring delusions, hidden influences, and the seductive appeal of esoteric claims that promise secret knowledge while offering little practical truth. Across its seven chapters, the book challenges readers to look past illusion and authority toward a more rational, humane understanding of life. It resists reducing people to mechanical or merely biological terms, insisting that consciousness, morality, society, and creativity cannot be explained by analogy alone. Instead, it argues for the ethical, spiritual, and intellectual significance of knowledge that genuinely serves ordinary life. Analytical, skeptical, and deeply reflective, the text invites readers to reconsider the value of civilization itself and the place of science and art within it.
