Answer:
The thinker who most influenced Sir Charles Trevelyan was Thomas Malthus.
Step-by-step explanation:
Sir Charles Trevelyan was an intelligent and upright man before his actions, but he could become insensitive. He was a British official and essential for the reform process for the British civil service.
In spite of all the excellent work that was doing his good job, he was overshadowed by the radical measure he took in the face of the plague of the potato and the great famine of 1840. The people considered that the decision not to help Ireland at the time indicated and the strong statements he made, identified Sir Charles with a genocidal thought before the Irish.
Many think that these decisions had to do with the influence of what was his economics professor Thomas Malthus.
Mr. Malthus considered in his theory of the population that the population would increase while food production would not do so in the same way, which would lead to a shortage of a long time that would cause the birth rate to decrease.
So it is said that Sir Charles Trevelyan thought the same and for that reason were his actions.
