[Verse 1]
Beyond the binary of yes and no
Where truth and falsehood used to reign
Deontic logic starts to grow
With operators that break the chain
Obligations dance with permissions here
While prohibitions guard the gate
Four symbols make the rules crystal clear
In this normative landscape we create
[Chorus]
O for ought, what must be done
P permits what's allowed to run
F forbids what can't occur
E exempts when lines get blurred
Shall and may and shall not flow
Through the logic we should know
Beyond true-false, we find the way
In deontic's moral display
[Verse 2]
Security teams shall review each quarter
Access privileges under scrutiny's lens
O wraps around this standing order
Making obligations that never bend
When M-F-A cannot deploy its shield
Enhanced logging takes the stage
Conditional arrows help us wield
Compensating controls on policy's page
[Chorus]
O for ought, what must be done
P permits what's allowed to run
F forbids what can't occur
E exempts when lines get blurred
Shall and may and shall not flow
Through the logic we should know
Beyond true-false, we find the way
In deontic's moral display
[Bridge]
Modal operators paint the scene
Where duty meets what's legally sound
Not just what is, but what should be
In formal rules where sense is found
Predicates carry the weight of action
While variables hold the who and when
Management controls find satisfaction
In this logic beyond mortal ken
[Verse 3]
From policy statements to code translation
Every shall becomes an O
Every may finds its permission station
While forbidden things learn where not to go
Exceptions carved with careful precision
When standard rules cannot apply
Deontic logic aids decision
In the space where ought and is collide
[Chorus]
O for ought, what must be done
P permits what's allowed to run
F forbids what can't occur
E exempts when lines get blurred
Shall and may and shall not flow
Through the logic we should know
Beyond true-false, we find the way
In deontic's moral display
[Outro]
Four operators standing guard
Over rules that shape our world
Making obligations less hard
When properly unfurled
