This quote by William Cowper is a suggestion that even if something can not be confirmed, it does not suggest that it does not exist. It is a suggestion to not jump to conclusions as well as to keep an open mind. It is a pointer to not assume something is not real even if there is no evidence to support it. It is a pointer to not be as well fast to disregard something as false just because there is no proof of its existence. It is a suggestion to be open up to the opportunity that something might exist also if there is no proof of it. It is a pointer to not be too fast to judge and also to be happy to consider all opportunities. It is a reminder to not be also quick to disregard something as false even if there is no evidence of its presence.
