“Whatever tends to lighten one's burden must be examined carefully. For although such alleviation is sometimes justified and reasonable, it is most often a deceitful prescription of the evil inclination, and must, therefore, be subjected to much analysis and investigation.”

An Essay on the Beautiful
Context: Perhaps, the good and the beautiful are the same, and must be investigated by one and the same process; and in like manner the base and the evil. And in the first rank we must place the beautiful, and consider it as the same with the good; from which immediately emanates intellect as beautiful. Next to this, we must consider the soul receiving its beauty from intellect, and every inferior beauty deriving its origin from the forming power of the soul, whether conversant in fair actions and offices, or sciences and arts. Lastly, bodies themselves participate of beauty from the soul, which, as something divine, and a portion of the beautiful itself, renders whatever it supervenes and subdues, beautiful as far as its natural capacity will admit.
Let us, therefore, re-ascend to the good itself, which every soul desires; and in which it can alone find perfect repose. For if anyone shall become acquainted with this source of beauty he will then know what I say, and after what manner he is beautiful. Indeed, whatever is desirable is a kind of good, since to this desire tends. But they alone pursue true good, who rise to intelligible beauty, and so far only tend to good itself; as far as they lay aside the deformed vestments of matter, with which they become connected in their descent. Just as those who penetrate into the holy retreats of sacred mysteries, are first purified and then divest themselves of their garments, until someone by such a process, having dismissed everything foreign from the God, by himself alone, beholds the solitary principle of the universe, sincere, simple and pure, from which all things depend, and to whose transcendent perfections the eyes of all intelligent natures are directed, as the proper cause of being, life and intelligence. With what ardent love, with what strong desire will he who enjoys this transporting vision be inflamed while vehemently affecting to become one with this supreme beauty! For this it is ordained, that he who does not yet perceive him, yet desires him as good, but he who enjoys the vision is enraptured with his beauty, and is equally filled with admiration and delight. Hence, such a one is agitated with a salutary astonishment; is affected with the highest and truest love; derides vehement affections and inferior loves, and despises the beauty which he once approved. Such, too, is the condition of those who, on perceiving the forms of gods or daemons, no longer esteem the fairest of corporeal forms. What, then, must be the condition of that being, who beholds the beautiful itself?

An Old Man's Thoughts on Many Things, Of Education I
Context: We must do something to lead boys to look at the wonderful objects by which we are surrounded, and to examine them carefully. I don't think that lectures are of much use. They will now and then amuse, and may teach boys a little; and if the lectures are followed by examinations, they will teach more.

Parallel Lives

Hagakure (c. 1716)
Context: Although all things are not to be judged in this manner, I mention it in the investigation of the Way of the Samurai. When the time comes, there is no moment for reasoning. And if you have not done your inquiring beforehand, there is most often shame. Reading books and listening to people's talk are for the purpose of prior resolution.
Above all, the Way of the Samurai should be in being aware that you do not know what is going to happen next, and in querying every item day and night. Victory and defeat are matters of the temporary force of circumstances.
