"Every inductively derived scientific generalization must ... remain 
forever tentative. ...
[S]cientific truth is also subject to cultural limitations - 
scientists live and work within the ethos of their culture and time 
period. ... (There are) five limitations - spatial, temporal, 
logical, cultural, empirical."
