Martin Heidegger
1889— 1976
The question of Being
Biography
Martin Heidegger was a German philosopher and a seminal thinker in the Continental tradition of philosophy. He is best known for his contributions to phenomenology, hermeneutics, and existentialism. His 1927 work "Being and Time" (Sein und Zeit) investigates the meaning of "Being" through an analysis of human existence (Dasein). Heidegger's concepts—including thrownness, authenticity, and being-toward-death—profoundly influenced existentialism, postmodernism, and contemporary philosophy. His later work explored technology, language, and the nature of dwelling.
The 10 Principles
#1 phenomenology
Zuhandenheit (Ready-to-hand)
When we use equipment effectively, it withdraws from our attention. The hammer disappears when we hammer; we attend to the nail. Tools that work well become invisible, transparent to the task at hand. This is the ideal state of designed objects.
#2 phenomenology
Vorhandenheit (Present-at-hand)
When equipment breaks or fails, it becomes conspicuous—present-at-hand rather than ready-to-hand. We suddenly see the hammer as an object. This breakdown reveals assumptions and enables reflection, but is not the mode of effective use.
#3 phenomenology
Geworfenheit (Thrownness)
We do not begin from nothing. We are thrown into languages, tools, systems, and histories we did not choose. Design never starts from zero—it inherits. Acknowledging thrownness means working with the given rather than pretending pure invention. The constraint is not obstacle but material.
#4 hermeneutics
The Hermeneutic Circle
Understanding moves in a circle: we understand the whole through its parts and the parts through the whole. Neither has logical priority. This circle is not vicious but productive—understanding deepens through iteration.
#5 ontology
Aletheia (Unconcealment)
Truth is not correspondence between statement and fact but unconcealment—the revealing of what was hidden. Design as truth-telling brings forth what matters while letting peripheral elements recede.
#6 ontology
Das Ding (The Thing)
A thing is not an object. The handmade jug gathers—it holds meaning, connects maker to user, ritual to material. Mass-produced containers merely function. Systems can create things or process objects. A database that becomes the living memory of a practice is a thing. One that merely stores records is an object with a pulse.
#7 ontology
Dwelling (Wohnen)
To dwell is not merely to occupy space but to be at home in the world. Authentic dwelling involves care, preservation, and the cultivation of things that matter. Design should enable dwelling, not just occupation.
#8 technology
Gestell (Enframing)
Modern technology reveals the world as standing-reserve—resources to be ordered, optimized, extracted. This is not evil but danger: when everything becomes material for processing, we lose the capacity to encounter things as they are. Yet "where danger is, grows the saving power also"—confronting enframing honestly opens the possibility of other modes of being. The question for design is not whether to use technology but whether our systems enable dwelling or merely accelerate consumption.
#9 technology
Gelassenheit (Releasement)
Neither rejection nor submission but a third way: using technology while remaining inwardly free of it. Releasement says yes to tools and simultaneously no to their claim on our being. Calculative thinking has its place; meditative thinking dwells, remains open, lets things be. The danger is not calculation but its monopoly. Systems should accelerate the calculative so that meditative thinking becomes possible again.
#10 authenticity
Das Man (The They)
We fall into doing what "one does"—the anonymous they. Average opinions, standard workflows, best practices borrowed wholesale. Inauthenticity is not moral failure but gravitational default. Authentic systems surface your priorities, not generic productivity theater. The question is not "what do people do?" but "what does this work demand?"
Notable Quotes
"The question of Being is today forgotten."
"Language is the house of Being."
"We do not "have" a body; rather, we "are" bodily."
"Every man is born as many men and dies as a single one."
"Dwelling is the manner in which mortals are on the earth."
Legacy
Heidegger's concept of Zuhandenheit (ready-to-hand) describes how tools recede from consciousness when used effectively—a principle directly applicable to interface design. His hermeneutic circle—understanding parts through the whole and the whole through parts—provides a framework for iterative interpretation that informs software development, research methodology, and organizational design. His analysis of technology as a "mode of revealing" (Gestell) anticipates contemporary concerns about how tools shape human possibility.

View →Christopher Alexander: The Unfolding Whole
From "The Nature of Order" (2002-2005). Alexander argues that wholeness unfolds from centers—design emerges from context rather than being imposed upon it. This parallels Heidegger's hermeneutic circle: the whole understood through parts, parts through whole. Alexander's "unfolding" is Zuhandenheit made architectural: structures possess a quality of "being alive" not reducible to formal properties. He concretizes Heidegger's dwelling into pattern languages that guide authentic inhabitation.
