Objectivity and subjectivity
In philosophy, an objective fact means a truth that remains true everywhere, independently of human thought or feelings. For instance, it is true always and everywhere that 'in base 10, 2 plus 2 equals 4'. A subjective fact is one that is only true under certain conditions, at certain times, in certain places or for certain people. For instance, 'That painting is beautiful' may be true for someone who likes it,
but not for everyone.
The above examples are non-controversial. There are, however, other issues considered objective by some, not all. The role of Evolution vs. Creation in the formation of living organisms is a typical example. Here, there are more objective arguments to support evolution than creation. Hence, an objective person will conclude that evolution is the most objective explanation. This illustrates that the objectivity of a theory does not depend on the approval of all. Sometimes, the objective opinion is held by a minority as, for example, Copernicus and Galileo's theories on the rotation of the Earth.
Objectivity versus neutrality
Neutrality is not synonymous with objectivity. In a controversy, an objective person will not remain neutral but will chose the side supported by the most objective arguments. Objectivity therefore requires a choice, which is often difficult and may prove to be erroneous, whereas neutrality requires no choice.
