Listening to Mark Carney, former governor of the Bank of England and frontrunner to replace Justin Trudeau as Liberal party leader, can be a dizzying experience. His mind brims with slogans — often sugary, often illogical — which he fires off like a tennis ball machine.

Take, for instance, his plea to a BBC audience a few years ago: “Ask not what the climate is doing to your country, but what your country can do for the climate.” Within minutes, the same audience was told “value can serve values,” “make your money matter,” “moral sentiments can rebalance market sentiments,” and finally, “private finance can bend the arc of history towards climate justice.”
