Perhaps the most characteristic example of unsystematic pessimism is the language of Ecclesiastes, who concludes that "all is vanity."
His work was too deliberately unsystematic ("keine Philosophie ist meine Philosophie") ever to make him a power in philosophy.
During this time he produced his Essay on Projects (1698), containing suggestions on banks, road-management, friendly and insurance societies of various kinds, idiot asylums, bankruptcy, academies, military colleges, high schools for women, &c. It displays Defoe's lively and lucid style in full vigour, and abounds with ingenious thoughts and apt illustrations, though it illustrates also the unsystematic character of his mind.
Throughout its history, therefore, "dialectic" has been connected with that which is remote from, or alien to, unsystematic thought, with the a priori, or transcendental, rather than with the facts of common experience and material things.
It is more easily matched in the unsystematic utterances of a man of the world like Montaigne.
