A person does have the right to change their mind, absolutely. I think people need to be careful with flip-flop claims, although at times it is appropriate.
Are you saying Lincoln changed his mind on his support of the Declaration of Independence?
he demonstratively was dragged kicking and screaming into the abolitionist camp (whom he had previously labelled "radicals")
And his dedication was to the principles he saw enshrined in the declaration, things like "all men are created equal"
I imagine that he would see that as the superior principle
which doesn't answer the question . . . .
"When is is justified to change your mind?"
He changed his mind on the slavery issue, while he continued to promote the DOI.
that this nation, under God, shall have a new birth of freedom—and that government of the people, by the people, for the people, shall not perish from the earth.
And if you don't agree with me, I'll enforce that freedom by force.
Sorry Abe that is not government by the people [states].
there is the considertion
does a person have the right to change their mind, ever? or if they change their minds, are they hypocrites?
When would such a thing ever ever ever be justified? (according to your principles)
