Poise shown by Turing for example in times past (7)
I believe the answer is:
balance
'poise' is the definition.
(I know that poise can be written as balance)
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for balance that I've seen before include "Sign" , "emotional stability" , "Weighing device" , "It weighs - the remainder" , "the unstable may lose before fall" .)
