Criteria of truth Whether someone's belief is true is not a prerequisite for its belief. On the other hand, if something is actually known, then it categorically cannot be false. For example, if a person believes that a bridge is safe enough to support her, and attempts to cross it, but the bridge then collapses under her weight, it could be said that she believed that the bridge was safe but that her belief was mistaken.
Since I have this idea the only thing that can explain this idea is God. This is kind of a cosmological argument for the existence of God.
Descartes epistemology we can trust reason logic and math. Because God is good and we have been created by Him, made for the world and the world for us, we CAN trust our senses so long as we do not extend our will to believe beyond what the evidence warrants.
Therefore we can trust the testimony of our senses, though not with the same degree of confidence that we trust our reason empirical knowledge. He never attempts to restore authority as a mode of justification.
Individual authority replaces institutional authority. Radical idea to Thomistic Scholasticism. Ushering in the Modern Era. This is one of the reasons that Descartes is called the first Modern Philosopher.
Our trust in our own mind and in our own senses depends on trust in a benevolent God. If you give up on God you have to give up of your own ability to know.
Absent the notion of God on what grounds can you trust your reasons or your senses? Problems with the Argument Offered Above: Do you really have a perfect idea of God or perhaps do you have an imperfect idea of a perfect being? He could have come up with it. But If he is doubting his senses why is he using a physical principle?
If he is doubting his reason why is he using a metaphysical principle?
But, if doubting reason one cannot use reason to justify reason. If X is identical to y then x and y must have all properties in common. This, he thinks, proves that the two are distinct. For instance, one can doubt one has a body but one cannot doubt one has a mind.
Thus the existence of body is doubtable while the existence of the mind is not. Does this prove that Peter Parker is not Spiderman? Further, the mind thoughts, ideas has no location; bodies always do.Descartes' epistemology in a nutshell.
1) We should doubt all that can be doubted, to find only that which is certain (build with firm foundation) 2) Senses can deceive us, but perhaps some sensory knowledge is certain? 3) In dreams there are clearly no senses that are certain; all is possible -- except math.
Epistemology is the area of philosophy that is concerned with knowledge. The main concerns of epistemology are the definition of knowledge, the sources of knowledge (innate ideas, experience, etc.), the process of acquiring knowledge and the limits of srmvision.commology considers that knowledge can be obtained through experience and/or reason.
René Descartes (—) René Descartes is often credited with being the “Father of Modern Philosophy.” This title is justified due both to his break with the traditional Scholastic-Aristotelian philosophy prevalent at his time and to his development and promotion of the new, mechanistic sciences.
Descartes's Basic Epistemological Argument: 1. Knowledge is justified true belief (JTB; the "classical" or "traditional" view) 2.
To be "justified" a belief must be shown to be necessarily true, or "certain.".
Defined narrowly, epistemology is the study of knowledge and justified belief. As the study of knowledge, epistemology is concerned with the following questions: What are the necessary and sufficient conditions of knowledge? Descartes's Meditations on First Philosophy remains one of the most widely studied works of Western philosophy.
