What is relative truth? 

A relative truth is a statement about some thing A that is true but not true about a 
different thing B even though the properties of A and B are indistinquishable from 
each other.

Example: In culture A it is ok to have more than one wife, In culture B is is not ok
to have more than one wife. 




However, you can't say that this statement is true for me and not true for someone else.
