Physics and chemistry alone cannot explain how a human being evolved out of the primeval protoplasm of the early seas. The ability to learn, memory and differential response to environment, is the endowment of mind. The laws of physics are not responsive to training; they are immutable and unchanging. The reactions of chemistry are not modified by education; they are uniform and dependable. Aside from the presence of the Unqualified Absolute, electrical and chemical reactions are predictable. But mind can profit from experience, can learn from reactive habits of behavior in response to repetition of stimuli.

Preintelligent organisms react to environmental stimuli, but those organisms which are reactive to mind ministry can adjust and manipulate the environment itself.

The physical brain with its associated nervous system possesses innate capacity for response to mind ministry just as the developing mind of a personality possesses a certain innate capacity for spirit receptivity and therefore contains the potentials of spiritual progress and attainment. Intellectual, social, moral, and spiritual evolution are dependent on the mind ministry of the seven adjutant spirits and their superphysical associates.

The seven adjutant mind-spirits are the versatile mind ministers to the lower intelligent existences of a local universe. This order of mind is ministered from the local universe headquarters or from some world connected therewith, but there is influential direction of lower-mind function from the system capitals.

On an evolutionary world much, very much, depends on the work of these seven adjutants. But they are mind ministers; they are not concerned in physical evolution, the domain of the Life Carriers. Nevertheless, the perfect integration of these spirit endowments with the ordained and natural procedure of the unfolding and inherent regime of the Life Carriers is responsible for the mortal inability to discern, in the phenomenon of mind, aught but the hand of nature and the outworking of natural processes, albeit you are occasionally somewhat perplexed in explaining all of everything connected with the natural reactions of mind as it is associated with matter. And if Urantia were operating more in accordance with the original plans, you would observe even less to arrest your attention in the phenomenon of mind.

The seven adjutant spirits are more circuitlike than entitylike, and on ordinary worlds they are encircuited with other adjutant functionings throughout the local universe. On life-experiment planets, however, they are relatively isolated. And on Urantia, owing to the unique nature of the life patterns, the lower adjutants experienced far more difficulty in contacting with the evolutionary organisms than would have been the case in a more standardized type of life endowment.

Again, on an average evolutionary world the seven adjutant spirits are far better synchronized with the advancing stages of animal development than they were on Urantia. With but a single exception, the adjutants experienced the greatest difficulty in contacting with the evolving minds of Urantia organisms that they had ever had in all their functioning throughout the universe of Nebadon. On this world there developed many forms of border phenomena—confusional combinations of the mechanical-nonteachable and the nonmechanical-teachable types of organismal response.
