In Lesson 2 of the Integral Mastery Primer, Ken Wilber explores the role of lines of development, also known as multiple intelligences. Just as the human body has many muscles, we each carry a range of intelligences, cognitive, emotional, moral, spiritual, aesthetic, interpersonal, and more, that have evolved to meet life’s countless challenges. Yet most of us only “train” a few of these lines, leaving strengths overdeveloped in some areas and serious blind spots in others.

Ken reveals how simply becoming aware of these intelligences can have a psychoactive effect, awakening dormant capacities and opening new dimensions of growth. This awareness creates the possibility for balance, creativity, and a fuller expression of human potential. By learning to recognize and nurture all of your intelligences, you begin to unlock a richer, more integrated way of living and being in the world.
