Plato and Aristotle
They emphasized that things are often very different from what they appear to be and that only the trained mind is prepared to see through the way things look to us on the surface (delusive appearances) to the way they really are beneath the surface (the deeper realities of life). -

History of Critical thinking

Socrates
Socratic questioning is used to describe a kind of questioning in which an original question is responded to as though it were an answer. This in turn forces the first questioner to reformulate a new question in light of the progress of the discourse. Socratic method is a form of inquiry and discussion between individuals, based on asking and answering questions to stimulate critical thinking and to illuminate ideas. -

Thomas Aquinas
To ensure his thinking he met the test of critical thought, always systematically stated, considered, and answered all criticisms of his ideas as a necessary stage in developing them. Aquinas heightened our awareness not only of the potential power of reasoning but also of the need for reasoning to be systematically cultivated and "cross-examined". -

Machiavelli
He critically assessed the politics of the day, and laid the foundation for modern critical political thought. He refused to assume that government functioned as those in power said it did. Rather, he critically analyzed how it did function and laid the foundation for political thinking that exposes both, on the one hand, the real agendas of politicians and, on the other hand, the many contradictions and inconsistencies of the hard, cruel, world of the politics of his day -

Francis Bacon
He recognized explicitly that the mind cannot safely be left to its natural tendencies. In his book The Advancement of Learning, he argued for the importance of studying the world empirically. He laid the foundation for modern science with his emphasis on the information-gathering processes. He also called attention to the fact that most people, if left to their own devices, develop bad habits of thought (which he called "idols") that lead them to believe what is false or misleading. -
Sir Thomas Moore
He developed a model of a new social order, Utopia, in which every domain of the present world was subject to critique. His implicit thesis was that established social systems are in need of radical analysis and critique. -
Hobbes and Locke
Both looked to the critical mind to open up new vistas of learning. Hobbes adopted a naturalistic view of the world in which everything was to be explained by evidence and reasoning. Locke defended a common sense analysis of everyday life and thought. He laid the theoretical foundation for critical thinking about basic human rights and the responsibilities of all governments to submit to the reasoned criticism of thoughtful citizens. -
Robert Boyle
In his Sceptical Chymist, Boyle severely criticized the chemical theory that had preceded him. -
Sir Isaac Newton
Newton, developed a far-reaching framework of thought which roundly criticized the traditionally accepted world view. He extended the critical thought of such minds as Copernicus, Galileo, and Kepler. -
Bayle, Montesquieu, Voltaire, and Diderot.
They all began with the premise that the human mind, when disciplined by reason, is better able to figure out the nature of the social and political world. What is more, for these thinkers, reason must turn inward upon itself, in order to determine weaknesses and strengths of thought. They valued disciplined intellectual exchange, in which all views had to be submitted to serious analysis and critique. They believed that all authority must submit in one way or another to the scrutiny of reasonab -
Adam Smith
Eighteenth Century thinkers extended our conception of critical thought even further, developing our sense of the power of critical thought and of its tools. Applied to the problem of economics, it produced Adam Smith’s Wealth of Nations. In the same year, applied to the traditional concept of loyalty to the king, it produced the Declaration of Independence. Applied to reason itself, it produced Kant’s Critique of Pure Reason. -
Comte and Spencer
Critical thought was extended even further into the domain of human social life by Comte and Spencer. Applied to the problems of capitalism, it produced the searching social and economic critique of Karl Marx. Applied to the history of human culture and the basis of biological life, it led to Darwin’s Descent of Man. Applied to the unconscious mind, it is reflected in the works of Sigmund Freud. -
William Graham Sumner
In the 20th Century, our understanding of the power and nature of critical thinking has emerged in increasingly more explicit formulations. In 1906, William Graham Sumner published a land-breaking study of the foundations of sociology and anthropology, Folkways, in which he documented the tendency of the human mind to think sociocentrically and the parallel tendency for schools to serve the (uncritical) function of social indoctrination.
