John Tierney writes another good article in science—this time in psychology. More specifically, it is about psycho-epistemology, though the neuroscientists working on it don’t know that. Skipping past these psychologists’ primitive theories about mind wandering (including daydreaming and zoning out) as being evolutionarily adaptive or as beneficial against boredom, we come to the real findings about human consciousness: that we have a conscious mind and that we have a subconscious.
[…] They found that when people’s mind wandered, the episode could last as long as two minutes.
Where exactly does the mind go during those moments? By observing people at rest during brain scans, neuroscientists have identified a “default network” that is active when people’s minds are especially free to wander. When people do take up a task, the brain’s executive network lights up to issue commands, and the default network is often suppressed.
But during some episodes of mind wandering, both networks are firing simultaneously, according to a study led by Kalina Christoff of the University of British Columbia. Why both networks are active is up for debate. One school theorizes that the executive network is working to control the stray thoughts and put the mind back on task.
Another school of psychologists, which includes the Santa Barbara researchers, theorizes that both networks are working on agendas beyond the immediate task. […]
And there you have it. Ayn Rand, by introspecting her own mind at work and by observing how people communicate their ideas, wrote way back in 1965: “Psycho-epistemology is the study of man’s cognitive processes from the aspect of the interaction between the conscious mind and the automatic functions of the subconscious.” [TRM “The Psycho-Epistemology of Art” 18a] Neuroscientists and psychologists would do very well if they but studied her writings.
It is a fact of nature that man has volition, and this faculty extends to his ability to control his conscious mind’s interaction with his subconscious, but only if he so chooses. Because of volition, human action is always purposeful (i.e., initiated and sustained for some purpose). Without a purpose, there is no human, i.e., rational, action. This, too, is a fact, and having a purpose is absolutely necessary if the conscious-subconscious interaction is to be under rational control. Because of the crucial role of purpose, every man needs to internalize a personal hierarchy of values in order to prioritize what he ought to think and do at all times. And this, too, is a fact. A man without values to aim for, without purpose, without active choice, reverts to the default “freedom” of being an animal, free to have random, aimless wandering, both physical and mental.
Want to be more creative? Simply choose to be! It is a simple procedure as far as I can introspect: [1] ask yourself questions of what you need to accomplish cognitively; [2] acquire facts and store your knowledge methodically; [3] give yourself standing orders to integrate for answers; [4] persist toward that purpose. Eureka!
