At that time, the Church pretended to have a full power over the truth: the truth was whatever the Church said and everything that the Church said was true.
The Scientific Revolution challenged this and introduced the idea that truth has to be supported by facts, which the Church was not happy to accept as it could not provide evidence for some of its claims.
That statement is false because looking at others' perspectives can help you deturmine what you think is right or wrong, good or bad, and makes sense or not.
