No sensible man (among the many things that have been written on this kind) ever imputed inconsistency to another for changing his mind.
[Lat., Nemo doctus unquam (multa autem de hoc genere scripta sunt) mutationem consili inconstantiam dixit esse.]
I shall do less whenever I shall believe what I am doing hurts the cause and I shall do more whenever I shall believe doing more will help the cause. I shall try to correct errors when shown to be errors and I shall adopt new views so fast as they shall appear to be true views.
And if joy were not on the earth,
There were an end of change and birth,
And Earth and Heaven and Hell would die,
And in some gloomy barrow lie
Folded like a frozen fly.
