Sir Henry returned to the Coleworths a few days later. Towards the end  of the conversation-filled meal, Catherine asked Sir Henry, "If  we do  not agree with the dialectic process of thesis, antithesis, and   synthesis, what is the good of a conversation? Do we always need to   maintain diversity?”
Glad that she was keeping up with the  conversation, Sir Henry explained, "Diversity  will always be maintained  because everything imagined already exists,  or else it could not be  imagined. If a synthesis is created, it becomes a  third thing. The  third thing may be preferable to both conversants, but the  other two  things should not be seen as being destroyed by the process.  They  remain options. People tend to like to burn bridges because keeping  the  other options open produces anxiety and insecurity. I suggest that  the  reason for the insecurity does not lie in the likelihood of a  person  changing their mind, but in the individualized value of necessity   placed on one of the options to the exclusion of the rest. This is not   to say that one option should not be thus valued, but the insecurity   associated with it may have unhealthy factors attached. Reasons become   all-important. Not objectives. Determining reasons then becomes the goal  of conversation. Could your reason for asking be based on a fear of  silence?"
"Hmm. Perhaps. Silence and the connotation of lack of relationship that goes along with it."
"Ah.  Relationship is the mysterious element when things are allowed to  maintain their diversity. What would conversation be like then,  individuals explaining their differences?"
"I suppose a response could be to point out similarities."
"Similarities  amongst diverse individuals. One could be afraid, again a reason, not a  negation of the possibility, of losing individuality if similarities  are focused on."
"Then one could discuss the value of fear or move beyond that to the relationship of similarity to diversity."
"How  like a woman to keep bringing it back to relationship! Or how about a  comparison, contrast of synthesis to relationship? Actually, I wonder if  there is such a thing as a synthesis. In chemistry, a solution is able  to retain the properties of both the solvent and the solute, though the  solvent keeps its dominant physical properties."
"When a person  drinks a glass of highly concentrated salt-water, which are you most  aware of, the water or the salt?" Catherine said, not the least  flustered.
Sir Henry, however, was. He quickly recovered. "Tasting being the required step to detect the diversity."
Now it was Catherine’s turn to fluster. The others busied themselves preparing the table for clearing.
"Comparing and contrasting tasting to the other senses involved, mainly sight and touch, would be an interesting conversation."
"Maybe  too interesting, which would be a reason not to have it now." Then to  the family, "Thank you for the delightful evening. I must be going."
