Please provide a 2000 words essay that contain introduction, body and conclusion. Please use this essay main thesis: the science is not the only form of progress and we need reconciliation between science and other forms of progress. During the essay the argument and taking a position in the argument is important and we need to provide sone counter arguments too. The essay topic is: What is the relationship between ‘science’ and ‘progress’? Is scientific progress always a good thing? Is science the only ‘kind’ of progress available to us? What other forms of ‘progress’ might exist?
