"If the dispositions of the parties are ever so well known to each other, or ever so similar before-hand, it does not advance their felicity in the least. They always continue to grow sufficiently unlike afterwards to have their share of vexation; and it is better to know as little as possible of the defects of the person with whom you are to pass your life." (Ch. 6)

I do not suppose you are completely serious but I think Charlotte’s philosophy that “Happiness in marriage is entirely a matter of chance” is rather naïve or a rationalization because it is nonsensical. Of course happiness with any partner cannot be guaranteed but purposely selecting a spouse you understand is stupid and delusional with poor values and is in no way your equal can only decrease the chance of happiness in marriage. I think Charlotte is right that disposition can change over time but that such changes are always vexing and a source of discontent is not true and the larger problem with her choice, that she seems to ignore, is that what rarely changes are essentials such as intelligence, character and values and she does not respect or esteem Mr. Collins now so I do not see how she will when they are married. The only advantage, if it can be called so, in Mr. Collins’ character to Charlotte so far has been his gullibility which made it easy for her to manipulate him into proposing but this characteristic will likely only contribute to her inability to respect and esteem him especially the more she takes advantage of it. Familiarity can breed contempt as the old saying goes. I do not know why Mr. Bennet married a woman so unequal in understanding and incompatible with his tastes but is it obvious his situation does not always promote his ability to treat his wife with respect and kindness. Charlotte has chosen to walk same road—of course whether she travels it in the same manner as Mr. Bennet is yet to be seen but even if she behaves better I fear instead of leaving happiness to chance she is throwing it on the wayside and leaving it behind.
