Together with Sartre, Merleau-Ponty was the foremost French philosopher of the post-war period and Phenomenology of Perception, first published in 1945, is his masterpiece. What makes this work so important is that it returned the body to the forefront of philosophy for the first time since Plato."
Phenomenology of Perception (Merleau-Ponty) -- groundbreaking analysis of "the thickness of things" implicit within perception
Labyrinths (Borges) -- masterful explorations of time, thought, infinity... certain passages of this collection surface in my mind on a weekly basis
Civilization and Capitalism (Braudel) -- telescopes seamlessly from the microscale to the macroscale, granting a synoptic view of the modern world
This opens up onto philosophical traditions that have mostly been obscured behind modern ideas about us being like computers, but you may want to consider something like Merleau-Ponty's The Phenomenology of Perception (or if you're really strong of heart, Husserl's Crisis of European Sciences and Transcendental Phenomenology).
1. Maurice Merleau-Ponty - The Phenomenology of Perception
2. Simone de Beauvoir - Ethics of Ambiguity
3. Friedrich Nietzsche - Will to Power
I'd highly recommend NOT reading Being and Time by Heidegger - you'll want to stab your eyes out ten times.
Outside of pure philosophical texts and more emphasis on fictional works related to philosophy, I'd suggest indirect material that encourage ideas of subjective perception and point-of-view. Examples are works by Franz Kafka, Ryu Murakami and William S. Burroughs.
For ethnography I don't have any recommendations. I've read books largely to complement my thinking, phenomenology and existentialism. Here's what I've read (notable ones):
Being and Time – Martin Heidegger
The Principle of Reason – Martin Heidegger
Phenomenology of Perception – Maurice Merleau-Ponty
New Reflections on the Revolution of Our Time – Ernesto Laclau
Introduction to Metaphysics – Martin Heidegger
The Basic Problems of Phenomenology (Studies in Phenomenology & Existential Philosophy) – Martin Heidegger
History of Western Philosophy – Bertrand Russell
The Presentation of Self in Everyday Life Erving Goffman uses the metaphor of theater to explain how we perform roles https://en.wikipedia.org/wiki/The_Presentation_of_Self_in_Ev...
I would say How to Do Things With Words by JL Austin which talks about the power of words to bring things into existence but it really gets into too much detail for me. https://en.wikipedia.org/wiki/J._L._Austin#How_to_Do_Things_...
Similarly Phenomenology of Perception by Merleau-Ponty really influenced me but it is really really really long and dense. https://en.wikipedia.org/wiki/Phenomenology_of_Perception
