The statement "we wish to get at it by degrees" by Parsons suggests that he is more moderate in his approach. The phrase "by degrees" implies a gradual and incremental approach, rather than a sudden and radical one. This suggests that Parsons is not looking to make drastic or immediate changes, but instead is looking for a more measured and gradual approach to achieve his goals. This is consistent with the idea of being moderate and not wanting to take radical steps.
