Another shift in the view on thinking began with the dawn of the Renaissance and continued into the 17th and 18th centuries. A movement began that shifted attention away from the belief that truth was divinely inspired by God and that the individual was incapable of discerning what is real or what is truth. Philosophers, like Descartes and Locke, believed to be true what they saw with their own eyes and experienced with their senses. Rather than assuming God played the key role in the universe, humans began to be the standard for judging what was real and what truth was. Human intellect was deemed capable of discriminating between truth and error. Certain defined methods for discovering truth and evaluating evidence came to be considered reliable and sufficient for discovering truth. Thinking focused more on observation, experience, rational thought, and the scientific method, rather than solely on God and tradition.
