order to formulate some explanations for Plato's Problem, our conscious awareness limits our experience; nevertheless, it seems as though some stimuli that are sensed by our sensory registers, although seemingly rejected by conscious awareness, are actually retained and abstracted into our memories for further processing. All of our fully functioning perceptual faculties enhance, supplement, and optimize our experiences. Long-term memory (LTM) This LTM availability/accessibility dichotomy is analogous to a more contemporary explanation of Plato's doctrine of reminiscence, which postulates that an individual hedge as a result of information carried over from past lives. While evidence for or against immortality is outside the bounds of scientific research, one can see similarities between LTM availability/accessibility and the doctrine of reminiscence. LTM availability is highly unrestricted and practically unlimited as a storage system while LTM accessibility corresponds to what we can actually recall at any given moment. Plato, through his doctrine of reminiscence, would say that knowledge available through reminiscence is practically unrestricted but we are not cognizant of many of those ideas because they have yet to be recalled. Implications Various implications arise from the research and theorizing on Plato's philosophy, linguistics, perception, and cognitive structures. Debates over epistemology have been around since antiquity. In historical philosophy, the debate has been between rationalism and empiricism. In contemporary psychology, the debate is between biology (nature) and environment (nurture). Rationalism is a philosophical and epistemological perspective on knowledge that claims, at its most extreme, that reason is the only dependable source of knowledge; moreover, rationalists assert that a priori knowledge is the most effective foundation for knowledge . Empiricism, on the other hand, argues that no knowledge exists prior to experience; therefore, all knowledge, as well as thought, comes from experience. The nature and nurture debate is not identical, and yet has parallels to the rationalism versus empiricism debate. Those who claim that thought and behavior result from nature say the cause is genetic predisposition while those who argue for environment say that thought and behavior are caused by learning, parenting, and socialization. In contemporary philosophical, linguistic, and psychological circles, it is rare to maintain an unwavering stance on either of these extremes; most fall toward the middle. The ideas of "nature and nurture" or "innateness and environmental input" are no longer perceived as mutually exclusive. Instead, researchers point to a necessarily interactive relationship in order for thought and behavior to occur. In Plato's
