Cell theory critique


Critique on article  "A Brief History of the Hypothesis".

David J. Glass and Ned Hall described two different ideas to frame an experiment.  Two different philosophical ideas are described in their paper, “A Brief History of the Hypothesis” which are the hypothesis and the model.  The hypothesis as described in this paper is the statement of fact that can be falsified. They believe that hypothesis is always unproven because they are made prior to the experiment. However, the model as defined by them is the method developed after data is obtained from the experiment. This is based on the inductive reasoning that methods the author concludes his paper stating that hypothesis should be neglected and reference should be taken from models to predict the further result of experiment.  The author espouse that the hypothesis over thinks about the context and it’s always falsified, however, scientific investigation should always be true. I cannot support the ideas of the author and the way he justified his claims.  I believe that hypothesis is essential to guide an experiment. Scientists cannot run an experiment without any pre- planned ideas or postulates.

 The model follows the concept of inductive reasoning which states that our past results can be taken as reference to proof for future was controversial. Hume goes against this concept and gave a new concept of radical skepticism. He supported the concept of radical skepticism and goes against the concept that past experience should be used to guide the future. This concept of inductive reasoning was supported by the philosopher Karl Popper. His philosophy supported the reasoning however, he suggested methodology to solve the problem of Inductive reasoning where “concepts are subjected to falsification.” Newton even goes against the concept of hypothesis.  Newton’s ideas were that even in his creation of physical and mathematics world was based on the conclusions. If we are to follow this logic then scientists in the medical field, especially doctors and health practitioners should stop providing medicine and taking care of patients, which makes uses the concept of past experience to cure patients.

It was confusing that during early stages of renaissance period there was confusing about the use of hypothesis in scientific experimentation. The controversy on hypothesis was fueled by Galileo because his minding in mathematical world was not based on hypothesis. Even, the concept of inductive reasoning was criticized because things that happened in past was not even valid during the age of Galileo.  There was assumption that his results of falling apple form tree were based on series of data’s.

Hypothesis guides our experiment. So, I support hypothesis in scientific world though it gets falsified. In real the hypothesis is not falsified, it shows the pathway that verifies the hypothesis. Science is based on the assumptions that we can make observation and this will lead us to the reality. Science cannot prove science itself, it’s like moving in a circle that will be arguing itself. Without hypothesis the scientific method will fall apart.
