Some impose upon the world that they believe that which they do not; others, more in number, make themselves believe that they believe, not being able to penetrate into what it is to believe.

There are people who profess something they privately doubt, and a larger number who have never checked whether they believe it at all. The second group is not lying. They took up a position the way you take up a habit, and have never sat with the question of what holding it would actually require of them.

Take one thing you would say you believe and ask what you would be doing differently if it were fully true for you. If the answer is nothing, you may be holding an affiliation rather than a conviction. That is worth knowing before someone tests it for you.
