Reflexive essays often focus on an experience and your explanation of how that experience changed you or aided in your growth as an individual. In short, reflexiveness achieves learning but also leaves you changed as a result. Often a challenging form of learning, reflexive essays are important for developing critical thinking skills and learning how to express opinions in greater depth. Because reflexive essays center on your perspective of a particular experience, teachers often assign a journal, log, or diary to record your intellectual journey with the assignment. Unless otherwise directed, you should write reflexive essays in the first person and past tense, and frame them in a logical order.
A copy of the fifth edition of the Essais with Montaigne's own "C" additions in his own hand exists, preserved at the Municipal Library of Bordeaux (known to editors as the "Bordeaux Copy").  This edition gives modern editors a text dramatically indicative of Montaigne's final intentions (as opposed to the multitude of Renaissance works for which no autograph exists). Analyzing the differences and additions between editions show how Montaigne's thoughts evolved over time. Remarkably, he does not seem to remove previous writings, even when they conflict with his newer views.
Aristotle's writings were preserved by his student Theophrastus, his successor as leader of the Peripatetic School. Theophrastus' pupil Neleus and his heirs concealed the books in a vault to protect them from theft, but they were damaged by dampness, moths and worms. The books were found around 100 BC by Apellicon, who brought them to Rome. In Rome, scholars took interest in the works and prepared new editions of them. The writings of Aristotle that we have today are based on this collection. Overall, Aristotle wrote three types of works: dialogues or other works of a popular character, collections of scientific data and observations, and systematic treatises. His philosophy can be divided into four main areas: 1) Logic; 2) Theoretical Philosophy, including Metaphysics, Physics and Mathematics; 3) Practical Philosophy, such as Ethics and Politics; and 4) Poetical Philosophy, covering the study of poetry and the fine arts.
