Honest disagreement is often a good sign of progress

Honest disagreement is often a good sign of progress.

Mahatma Gandhi

Nodding one’s head in agreement when reading an inspiring quote like this is one thing. Furthering the thought with questions, is another thing.

For me, two questions come to my mind:

(1) What is an “honest” disagreement?

(2) How does one create an environment where people can “honestly disagree”? (I am thinking of this question more in the context of the workplace and less in politics.)

What are your thoughts?
