There are no better terms available to describe [The] difference between the approach of the natural and the social sciences than to call the former ''objective'' and the latter ''subjective.'' ... While for the natural scientist the contrast between objective facts and subjective opinions is a simple one, the distinction cannot as readily be applied to the object of the social sciences. The reason for this is that the object, the ''facts'' of the social sciences are also opinions -- not opinions of the student of the social phenomena, of course, but opinions of those whose actions produce the object of the social scientist.
~ Friedrich August Von Hayek - [Science and Scientists]
