Rodin’s Thinker, originally created to represent Dante Alighieri contemplating his epic poem The Divine Comedy, has become a symbol of critical thinking and the pursuit of knowledge and truth.
In White Rose Magazine’s exhibit, The Thinker, we highlight six foundational thinkers who have helped formulate methodologies to pursue truth. The Aristotelian and Socratic methods devised disciplines, through questioning, deductive reasoning, and empirical observations to challenge assumptions and arrive at an objective truth. Plato, from the standpoint of idealism, formulated an external idea of “the Good.”
Similarly, Aquinas and Maimonides pursued similar methods for theological and scientific arguments, and Francis Bacon, known as the father of the scientific method, applied these techniques and others in creating his Baconian method.
These six thinkers helped lay the foundation of modern critical thinking methodologies.
