The essence of design is deeply rooted in the core identity of creations made by humans. It serves as a foundational element that reflects the nature and purpose of the object or idea, influencing its outward appearance and functionality. This inward essence eventually manifests in various external forms and layers, which can change while still retaining the core principles of design.

In Walter Isaacson's biography of Steve Jobs, this quote encapsulates the idea that true innovation in design goes beyond aesthetics. It highlights how a well-thought-out design embodies the soul of its creator and reveals their vision through its various iterations, ultimately enhancing user experience and connection to the product.
