How did humans perceive life, the world, and one another a million years ago? How was it different from the way we perceive life today? What does 'a million years' mean in a time when there is no time? Two dimensions—primitive and civilized—collided in prehistory causing chaos to the primitive world we call Earth. In Forbidden Dimensions, psychologist C. G. Browne argues that ancient humans were innately constructed not to change, and that the concept of development is at the heart of some devastating psychological and social problems we are facing today as a species. Has the ability to develop really evolved or has it been woven in? Will progress ever stop? Will humankind ever arrive at its destination or are we stuck in a trap, destined to time travel, modify, and adapt for eternity? Forbidden Dimensions is a challenging and philosophical exploration of past, present, and future Mind.
