Is the scientific method the only way to acquire knowledge?

I’m actually asking two questions here: My first question is whether you think that the scientific method is the only way to acquire knowledge? This question can pertain to acquiring knowledge of any entity, phenomena or anything of the mind.

My second question is whether or not you think that the scientific method is the best way to produce a morally sound and civilized society?

I’m asking this question in the general section because this is an important issue to me, and I want both of my questions to be addressed.
