Berkeley's non-cognitivism

A Caius theology student, can omniscience
and freedom coexist? Do angels smell of thyme?
God knows. I quit, open a wine-bar in Hoxton,
small courtyard out back for snacks and salsa.
'You're going to paint it that?' my ex-girlfriend Liz
enquires. 'I like red. Besides, what does it matter?
Colours are perceptual.' Her younger brother
helps me. We get on ok despite his preference
for melody-lite drum n'bass and dope. One time,
Liz discovers us together in bed. 'I'm not bent!'
he assures her. She looks unconvinced. 'Like
Berkeley?' I suggest. 'Was he a non-cognitivist?
Who can say for certain?' Now bewildered, 'Mike,
sleeping with my brother is wrong!' I shrug.
'What you mean is you don't want me to.'
