John Dewey's The Quest For Certainty

Decent Essays
Following I will show, that Dewey’s Pragmatism , especially the parts explained in his book “The Quest for Certainty”, does not debut Determinism by showing that his explanations are focusing on the way we achieve proper knowledge rather than on reality itself.
In his book Dewey starts his book by summing up how the dualism of thinking and acting developed in the past. Relating to Newton, Einstein and Heisenberg he then shows the development within Physics from this dualism to an act and experiment related way of achieving acquiring knowledge. He points out the great success of this change and finally suggests changing Philosophy as well. In his opinion it should not be based upon the idea of an antecedent Reality with a priori knowledge and its effects, but rather use old knowledge as base for further experiments to gain new knowledge.
From Einstein’s Theory of Relativism he extracts the idea of everything being seen in relation to its environment. Following this he adds Heisenberg’s Uncertainty principle. Originally it says, that the light, which is reflected from

If we continue to imply a priori knowledge and a preexisting Reality, which all our knowledge is based on, to achieve new knowledge we cannot develop as good and fast as the natural science. Rather we should give up these ideas and accept that some old information might be wrong but lead us to new experiments and new knowledge. In this way, we can push Philosophy on the same level as Physics. The only thing we might have to do is to abandon our quest for certainty, which we will not be able to reach and observe, but rather look for security, as the physicists do with their probability, and come as close as possible and necessary to certainty.
Takin this all into account and linking it to the initial question we have to admit that Determinism is not touched by Dewey’s Pragmatism. It can neither be explained nor rebut by
