Obscure marginal seat, one I could secure all things being equal? (14)
I believe the answer is:
egalitarianism
'secure all things being equal?' is the definition.
I can't judge whether this definition defines the answer.
'obscure marginal seat one i' is the wordplay.
'obscure' indicates an anagram.
'one' becomes 'i' (Roman numeral).
'marginal'+'seat'+'i'+'i'='marginalseatii'
'marginalseatii' anagrammed gives 'EGALITARIANISM'.
'could' acts as a link.
Can you help me to learn more?
(Other definitions for egalitarianism that I've seen before include "Belief that all are equal" , "radical policy" , "Belief in the equality of men" .)
