Final answer:
The Peripatetic Axiom, which states that nothing is in the mind that was not first in the senses, was formulated by Aristotle. This principle underscores the importance of sensory experience in the acquisition of knowledge, epitomizing Aristotle's empirical approach as opposed to Plato's idealism.
Step-by-step explanation:
Aristotle, the renowned student of Plato and a pivotal figure in Western philosophy, is credited with articulating the Peripatetic Axiom, stating that nothing is in the mind that was not first in the senses. This principle reflects Aristotle's empirical approach to knowledge, affirming that all cognitive processes are rooted in sensory experience.
The term Peripatetic Axiom, though not explicitly used by Aristotle himself, is a modern designation encapsulating this fundamental idea linked to his teachings. Aristotle's philosophy significantly diverged from his teacher Plato's idealism, embracing a practical study of the natural world through observation and reason. This contrast is especially evident in the context of metaphysics and epistemology, areas in which Aristotle established the veneration of empirical evidence and sense data over abstract ideals. His approach laid the groundwork for later empiricists and had substantial influence on intellectual thought, including the work of St. Thomas Aquinas, who adopted the empirical view that the mind is a blank slate until it encounters sensory input.
