Instead, therefore, of all this pageantry, which seems so strongly to have acted upon your mind, I must inform you that there is no human being exposed to suffer a greater degree of hardship; he is often obliged to march whole days in the most violent heat, or cold, or rain, and frequently without victuals to eat, or clothes to cover him; and when he stops at night, the most that he can expect is a miserable canvas tent to shelter him, which is penetrated in every part by the wet, and a little straw to keep his body from the damp unwholesome earth.- "The History of Sandford and Merton", Thomas Day.
It is indeed true that those who are accustomed to the careful and systematic investigation of causes, who have been trained from their earliest years to recognize in the pomp and pageantry of the external world- and even to some extent in the working of the human mind and the structure of human society- the orderly sequence of natural law, will have a type and character of mind essentially different from those who have not passed through this discipline.- "The Unity of Civilization", Various.
