"As a rule we disbelieve all the facts and theories for which we have no use"

This quote by Gustave Flaubert talks to the propensity of humans to ignore truths and theories that do not have an immediate usage or function in their lives. It recommends that we are frequently quick to dismiss info that does not have an instant advantage to us, even if it is true. This can be seen in the way that individuals typically neglect scientific facts that do not have an instant influence on their lives, such as environment change or the effects of pollution. It also talks to the way that individuals typically disregard realities and theories that do not fit into their existing worldview, even if they are true. This quote works as a pointer to be unbiased and to consider all truths and theories, despite whether or not they have an instant usage or function in our lives.
