The justification for any course of action is often
jerry-rigged into the mission statement after the mission itself is well under
way; the why comes after the what has already been decided.
For instance, Alister McGrath points out this interesting
fact about Sigmund Freud, the father of psychoanalysis:
“Freud’s atheistic view of the origin of religion comes prior to his study of religion; it is not its consequence.”
In other words, Freud first decided on his theory then went
about doing the research to back it up, not the other way round. His theory did
not arise inductively from his studies but from his own prejudices.
