"If there is something that opens the horizons, it is precisely ignorance." 

I read this sentence by writer and diplomat Romain Gary during a train journey from New York to Washington. It takes me a few minutes to interpret the sentence taken out of its context.

I wonder if the term “ignorance” in the phrase should be interpreted as "non-knowledge" and, as such, if the status of “not knowing” could potentially stimulate curiosity and thus open the horizons, metaphorically speaking, of the mind.
