These things become the material cause of my laptop. To continue Aristotle’s sculpture idea this was the way in which the marble was moved from its state of potentiality to becoming the actual marble statue.He understood that each of the four causes was necessary to explain the change from potentiality to actuality.His first cause, the material, explained what the object or thing being described was made from.Unlike his teacher, Plato, Aristotle believed that the world could be explained by physical observation.This approach of using the five senses, cataloguing and categorising, is the foundation of scientific study. Plato believed that we needed to look beyond the physical for an explanation of the universe in the guise of the World of Forms. Aristotle’s understanding of the four causes begins with the assumption that is present in all Greek philosophy, the notion of pre-existing matter.A complete explanation of any material change will use all four causes.These causes are material, formal, efficient and final. Computers are made out of transistors and other electronic components.Aristotle describes and argues for the four causes in his books Physics and Metaphysics as a part of developing his philosophy of substance.He claims that there are four causes (or explanations) needed to explain change in the world.He observed the world around him and noticed that it was in a state of constant motion, a movement from potentiality to actuality This movement from potentiality to actuality lead Aristotle to the conclusion that there are stages in causation.He called these the four causes: Material, Efficient, Formal and Final causes.
