You're certain that you possess the Truth -- inevitably offered with an implied uppercase T -- and this certainty quickly devolves into dogmatism and righteousness, by which I mean a demonstrative, overweening pride in being so very right, in short, the arrogance of fundamentalism.
Esteu segurs que posseïu la Veritat -- inevitablement oferida amb una assumida [V] majúscula -- i aquesta certesa recau ràpidament en el dogmatisme i la rectitud, i em refereixo a un orgull demostrat, arrogant en ser tan correcte, breument, la arrogància del fundamentalisme.
