How we form general ideas—and how those ideas grow from concrete senses to abstract thought.
This volume traces the rising evolution of our mental powers, from basic perception to the deepest general notions. It explains how three main periods structure our thinking: before speech, with words, and with words that replace direct experience. The study draws on observations of animals, children, and deaf-mutes, and it shows how language, signs, and mental images shape what we know.
In clear, compact chapters, the author maps the path from simple impressions to complex theories. You’ll see how abstraction begins without language, then moves through language‑aided stages, and finally reaches a stage where words alone can stand for ideas. The book also outlines how these ideas are tested, organized, and refined across philosophy, science, and daily life.
- Learn about three forms of abstraction and how people picture general ideas: concrete images, visual/typographic representations, and auditory associations.
- Explore how key concepts like number, space, time, cause, and species develop from practical memory and experience.
- See how language and signs influence thought, and why some thinkers think in pictures while others think in words.
Ideal for readers of psychology, philosophy of mind, and the history of ideas, this edition offers a focused look at how humans move from seeing the world to naming and organizing it. Whether you’re new to the topic or brushing up on classical theories, you’ll gain a clearer sense of how abstract thinking grows from concrete beginnings.
