General agreement about an assumption is no guarantee that it is correct. It is historical continuity that maintains most assumptions – not a repeated assessment of their validity.

Periodic reassessment means looking again at things which are taken for granted, things which seem beyond doubt. Periodic reassessment means challenging all assumptions. It is not a matter of reassessing something because there is a need to reassess it; there may be no need at all. It is a matter of reassessing something simply because it is there and has not been assessed for a long time. It is a deliberate and quite unjustified attempt to look at things in a new way.
I thought about something and then I thought, Why did I think about that? I can have thoughts about thoughts!
There are two ways to slide easily through life: to believe everything or to doubt everything. Both ways save us from thinking. — Alfred Korzybski
