They Refused to Look Through the Telescope

There were churchmen and other contemporaries of Galileo who, standing fast on  convictions swotted up from the lore of Aristotle and his commentators, refused to look through the Italian's telescope.  Similarly, there are atheists and mortalists today who, standing fast on convictions derived from less reputable sources, refuse to engage in the spiritual practices which could serve as their 'telescope.' 

Just as the scientific attitude demands of us an openness to one range of experience, the religious attitude demands of us an openness to another.
