Please give a general introduction to the Metaphysical School

The Metaphysical School is a philosophical movement that emerged in the 17th century and focused on the study of the nature of reality. Metaphysics is the branch of philosophy that deals with the study of the fundamental nature of reality, including the relationship between mind and matter, substance and attribute, and cause and effect. The Metaphysical School emphasizes the importance of a priori knowledge and rational thought in understanding the nature of reality, as opposed to empirical observation and experimentation. Some of the key figures associated with the Metaphysical School include Rene Descartes, Gottfried Leibniz, and Baruch Spinoza. The school had a significant influence on the development of modern philosophy, particularly in the areas of epistemology, ontology, and ethics
