Democratic leaders, whose power is ultimately dependent on popular support, are held accountable for failing to improve the lives of their citizens. Therefore, they have a powerful incentive to keep their societies peaceful and prosperous. Natan Sharansky
This conviction of the solvability of every mathematical problem is a powerful incentive to the worker. We hear within us the perpetual call: There is the problem. Seek its solution. You can find it by pure reason, for in mathematics there is no ignorabimus. David Hilbert
If governments did not mislead their citizens so often, there would be less need for secrecy, and if leaders knew they could not rely on keeping the public in the dark about what they are doing, they would have a powerful incentive to behave better. Peter Singer
