Could someone mark my section 3 BMAT essay:
'Science is a great and glorious enterprise - the most successful, I argue, that human beings have ever engaged in. To reproach it for its inability to answer all the questions we should like to put to it is no more sensible than to reproach a railway locomotive for not flying or, in general, not performing any other operation for which it was not designed.'
(The Limits of Science, Peter Medawar)
From the statement, I understand that science has addressed and found solutions and broadened our understanding of many different concepts. Science has no clear specific operation for which it was designed but essentially is an attempt by human beings to find a cause and reason for everything in existence.
An underlying principle of science is to suggest a plausible mechanism or explanation to questions. An example is science has figured out how the body attempts to recover itself after an illness, which is done by the immune system and the action of B and T lymphocytes, which is a plausible explanation and has been proven through tests.
But on the other hand, science can only be advanced in certain cases if we know 'how' to advance it. For psychological disorders we attempt to find the basic root of the displayed abnormal behaviour caused by the mind, but there are no clear-cut ways, as the human mind is ultimately so complex that it hasn't fully been understood by science yet.
Another example of how science is limited is through its technological advancements. Science is unable to provide a definite answer to if extraterrestrial beings exist, because humans have not made enough progress yet to check out the whole universe and confirm if they exist. Although our knowledge and potential through science is gradually increasing, it relies primarily on human existence.
In conclusion, science can give plausible explanations for a number of cases, but its advancement is dependant on human advancements and so it is a mutual relationship between the two that gives rise to the whole concept of 'science'.
