The problem here is one which arises in relation to any study dealing with matters of profound human concern. Someone who is profoundly uninterested in political affairs is unlikely to make a good political scientist. But nor on the other hand is the most passionately committed party politician. The general point might be put something like this. Where there is not enough love, there is likely to be a lack of penetration into the inwardness of the subject studied. But too much love may blind a man and prevent him from seeing some of the inherent problems and difficulties.
nor = 2. used before a positive verb to agree with something negative that has just been said
Nor already confirms a negative meaning (but with a positive verb), so why's on the other hand necessary? If I keep nor but remove on the other hand, then what happens?
Conversely, what if I remove nor and keep on the other hand?
Please explain the steps, thought processes; I’d like to try to resolve this myself in the future?
