It is evident to any one who takes a survey of the objects of human knowledge, that they are either ideas actually imprinted on the senses, or else such as are perceived by attending to the passions and operations of the mind, or lastly ideas formed by help of memory and imagination, either compounding, dividing, or barely representing those originally perceived in the aforesaid ways.
Ancient philosophy The pre-Socratics The central focus of ancient Greek philosophy was the problem of motion. Many pre-Socratic philosophers thought that no logically coherent account of motion and change could be given. Although the problem was primarily a concern of metaphysicsnot epistemology, it had the consequence that all major Greek philosophers held that knowledge must not itself change or be changeable in any respect.
Plato Plato accepted the Parmenidean constraint that knowledge must be unchanging. One consequence of that view, as Plato pointed out in the Theaetetus, is that sense experience cannot be a source of knowledge, because the objects apprehended through it are subject to change.
To the extent that humans have knowledge, they attain it Argumentative essay on john locke transcending sense experience in order to discover unchanging objects through the exercise of reason. PlatoPlato, marble portrait bust, from an original of the 4th century bce; in the Capitoline Museums, Rome.
Of the many literary devices Plato used to illustrate his theory, the best known is the allegory of the cavewhich appears in Book VII of the Republic. The allegory depicts people living in a cave, which represents the world of sense-experience.
In the cave, people see only unreal objects, shadows, or images. Through a painful intellectual process, which involves the rejection and overcoming of the familiar sensible world, they begin an ascent out of the cave into reality.
That process is the analogue of the exercise of reason, which allows one to apprehend unchanging objects and thus to acquire knowledge.
The upward journey, which few people are able to complete, culminates in the direct vision of the Sun, which represents the source of knowledge. Knowing also is a mental faculty, according to Plato, and therefore there must be a unique set of objects that it apprehends.
Roughly speaking, those objects are the entities denoted by terms that can be used as predicates —e. Plato is here distinguishing between specific triangles that are drawn, sketched, or painted and the common property they share, that of being triangular.
Unlike particulars, forms do not exist in space and time; moreover, they do not change. They are thus the objects that one apprehends when one has knowledge. Reason is used to discover unchanging forms through the method of dialecticwhich Plato inherited from his teacher Socrates.
Anyone who grasps these conditions understands precisely what being a brother is.
In the RepublicPlato applies the dialectical method to the concept of justice. Suppose one borrows a weapon from a person who later loses his sanity.
If the person then demands his weapon back in order to kill someone who is innocent, it would be just to lie to him, stating that one no longer had the weapon. In doing so he apprehends the form of justice, the common feature that all just things share.
But how should knowledge in general be defined? In the Theaetetus Plato argues that, at a minimum, knowledge involves true belief. No one can know what is false. People may believe that they know something that is in fact false.
But in that case they do not really know; they only think they know. Knowledge is more than simply true belief.An Essay Concerning Human Understanding John Locke’s Essay presents a detailed, systematic philosophy of mind and thought.
