Juan Vives (1493–1540) proposed induction as the method of study and believed in the direct observation and investigation of the study of nature. His studies focused on humanistic learning, which opposed scholasticism and was influenced by a variety of sources including philosophy, psychology, politics, religion, and history. He was one of the first prominent thinkers to emphasize that the location of a school is important to learning. He suggested that a school should be located away from disturbing noises; the air quality should be good and there should be plenty of food for the students and teachers. Vives emphasized the importance of understanding individual differences of the students and suggested practice as an important tool for learning.
