“The evil of marriage, as is it practiced in the European countries, extends further than we have yet described. The method is for a thoughtless and romantic youth of each sex, to come together, to see each other, for a few times, and under circumstances full of delusion and then to vow eternal attachment. What is the consequence of this? In almost every instance they find themselves deceived. They are reduced to make the best of an irretrievable mistake. They are led to conceive it their wiser policy, to shut their eyes upon realities, happy, if by any perversion of intellect, they can persuade themselves that they were right in their first crude opinion of each other. Thus the institution of marriage is made a system of fraud; and men who carefully mislead their judgement in the daily affair of their life, must be expected to have a crippled judgement in every other concern.”
