The most common sort of lie is that by which a man deceives himself: the deception of others is a relatively rare offense.

- Friedrich Nietzsche, The Antichrist

أكثرُ أنواعِ الكذبِ شيوعًا هي تلك التي يَخدَعُ بها المرءُ ذاتَه. الكذبُ على الآخرين نادرٌ مقارنةً بالأول.

— فريدريك نيتشه

Although generally considered by his contemporaries to be friendly and gentle, Leonardo was at times dark and troubled. His notebooks and drawings are a window into his fevered, imaginative, manic, and sometimes elated mind. Had he been a student at the outset of the twenty-first century, he may have been put on a pharmaceutical regimen to alleviate his mood swings and attention-deficit disorder. One need not subscribe to the artist-as-troubled-genius trope to believe we are fortunate that Leonardo was left to his own devices to slay his demons while conjuring up his dragons.

رغم أنّه اعتُبِر ودودًا ولطيفًا من قِبَل معاصِريه، إلّا أنّ ليوناردو دافنشي كان في بعض الأحيان سوداويًا ومهمومًا. مذكّراته تمثّل نافذةً لخياله الواسع وعقله المحموم والمهووس، وفي بعض الأحيان، السعيد.
لو كانَ ليوناردو طالبًا جامعيًا يعيش في مطلع القرن الحادي والعشرين، لربما وِصفَت له مجموعةُ أدويةٍ لتخفّفَ تقلباته المزاجية واضطراب الانتباه الذي لديه. لا يحتاج المرء ليؤمن بالصورة النمطية للفنّان المعذب ليُدرِك أنّنا محظوظون أنّ ليوناردو قد تُرِك لنفسه ليصارعَ شياطينه ويرسم تنانينه في ذات الوقت.

Blind people who can see with their ears

Blind people who see with their lower backs, and deaf people who hear with their wrists

Pagans are all those who say yes to life, and to whom “God” is a word signifying acquiescence in all things
