The modern philosopher in the quotation argues that Modern science is experimental because it uses the experiment to understand nature. According to him, this is true because nature can be explained by the cause-effect relationship. Modern science uses the experiment to prove events that are assumed to be true in advance. Before conducting the experiment we have assumptions or a theory in mind and we conduct experiment to prove them to be true. The theory itself, determines which experiment should be used and which results will be obtained. We get some results after experimenting, those results feed our theory. Based up on these theories we create new assumptions and from these assumptions a new theory is formed . Again to prove that newly formed theory we conduct experiments according to its own assumptions. Experiment turns into job of looking for answers to questions which come from the theory. Moreover those questions are dependent on assumptions. So we find ourselves in a circular reasoning when we are doing experiments. Here, experiment is done to confirm theory. There is no new innovation, we do experiment for finding out what's already there. Therefore, when the writer says "experiments are set up for the sole purpose of asking whether and how nature follows the scheme preconceived" he shows that he is a determinist and proves that there is a circular reasoning. Because in determinism events are determined by the former events, the pattern is determined. However this logic represents a basic limitation in the scientific description of nature because it excludes the chance factor, flexibility. Nature is not just a cause and effect relationship.
             To understand why this logic is a limitation to modern science we should examine what are the rules of this philosophy. In determinism the nature is seen as a closed system. In that closed system every event is the effect of the preceding one and at the same time c...
