While Adler may say that a text could be cleverer than you are (is this a direct quote? reference if so), there is an associative nature to our thinking by which one can read further into a text than anything which is actually present. Did the author really mean to "say" the additional associative material? Was it in their lived experience to make such tangential references which associate things in your mind as well?

One ought to be careful that an author can only mean something so far, unless one has much more experience with their additional works and context. If it's not there, does it really exist? Did they mean it?

These associative tricks are what can make texts much richer and deeper than they may have claim to be. Though this doesn't mean that they aren't good "conversation partners."
