believes in his or her morals have a great impact on the way they feel about themselves-—"mental strength can influence physical strength". Emotions, according to Vives, can be divided up into "Hot, cold, moist, dry, and varying combinations of the four". Personality disturbances with emotions could be fixed when applying the correct temperature on to the body. Memory Vives placed emphasis on memory. He defined memory as "…relating to the past, while perception relates to the present". "Memory is something that is retained by either externally or internally perceiving it". He especially emphasized how humans imagine something internally and connect it with an event in order to create a memory. This, according to Vives, makes information retrieval of memory easier. He touched on memories in which we are unaware of, otherwise known as the unconscious. He said information is the "Most accessible from memory when a certain amount of attention is given." According to Murray, Vives showed understanding of the modern-day conception of how humans process retrieval.

In terms of retaining memory, imagination was thought to play a key role, especially in children. He also believed in a theory that pointed towards the fact that memory can be improved with practice. He advised that "One should memorize something every day, even a useless quotation." Vives even touched on childhood memory-—he believed that children learn quickly because their mind is less cluttered with worries that adult minds have. Vives also believed that recall of memory is brought about by a concept in which the soul processes the memory. Vives himself had a recall experience as a child where he ate cherries when he had a fever. When he had cherries again as an adult, he "felt as though he was sick just as he was when he was a child." He found this remarkable and determined that memory can exist unconsciously for a very long time. He also believed that "memory declines every day that the mind is not exercised." Learning Vives used the word "intelligence" in a way that can be translated to the word "supervisor" as we know its meaning today: intelligence, according to Vives, involves functions directing attention from different kinds of stimulus. Intelligence is very much a cognitive structure according to Vives. When we learn, the memory
