Can You Show That We Don't Know Anything?Most people go through life without ever questioning the idea of knowledge. We all make statements every day such as 'I know X', and 'We all have knowledge of Y', yet when we truly examine what it means to 'know' something, the statements and ideals we take for granted become dubitable. In fact, it could even be argued that it is essentially impossible to know anything at all.Knowledge can be defined as 'justified true belief', yet what do we mean by "justified"? Is there any statement in life which can be justified to the point beyond doubt, whereby it becomes 'knowledge'? Perhaps the most difficulty arises when looking at truths concerning empirical knowledge from the external world. If I make a statement such as 'I know that there is a desk in front of me', then I am relying on my senses to provide me with reliable information about the empirical world. Yet can the senses necessarily be trusted? A Sceptic may take the view that our senses deceive us, and henceforth should not be taken as a reliable source of knowledge. Yet it is not only the senses that provide a problem for the epistemologist. How can we ever justify any belief? Surely, to ever have any true knowledge, we must f
He claims that because God is that than which none greater can be perceived (i. He therefore uses a mathematical model of building up a number of (what he considers to be) indubitable premises in an attempt to reach an equally indubitable conclusion. Descartes argues that God's guarantee only extends to our clear and distinct ideas, so God only guarantees the real existence of a world of extension and motion. Similarly, the ontological argument has been criticised on account of the huge assumption made in the first premise; that there is a perfect God; and the general weakness of the argument that anything perfect must exist. orm an indisputable criterion for truth. One way of accepting such truths is through the acceptance of Descartes' argument, yet as we have seen the argument is troubled, and encourages us to look for another source of knowledge. Next, he argues that even if our perceptions seem correct, there is nothing to say that we are not in a dream or suffering from a delusion of some sort. Descartes tries to provide justification through his 'cogito' argument, and then God's existence, but it could be argued that there is in fact no way of ever actually formulating any justification at all. But knowing that there is existence, in some shape or form, (for it could potentially be a disembodied existence), does not seem to be very impressive, as it gives us no knowledge about the external world whatsoever. ' Finally, Descartes argues that it is possible that there is 'some malicious demon of the utmost power', whose intention is 'to deceive me', therefore rendering questionable all of the things we take to be true. Whilst Berkeley's argument can perhaps be seen as dated and weak, he does raise an interesting point: Because we can never have certain knowledge of the external world through the senses (unless we adopt an argument such as Descartes involving a Deity), then we seem to become stuck on what Berkeley describes as the 'royal road to scepticism'. Hence, Descartes' argument seems to be flawed. The problem here is that obvious indubitable truths, such as 2+2=4, do not tell us anything interesting about the world, whilst beliefs about my own current experiences are very controversial. 3) I am not the cause of these states myself. In fact, it could be argued that living in such a world would be no different to living your entire life in a dream.
