Anxiety is a world in which: potentiality has no concrete ingress or in which actuality has no openness.

This statement captures a profound existential insight into the nature of anxiety, drawing from philosophical traditions—particularly those influenced by Aristotle's concepts of potentiality (dunamis: the capacity for change or possibility) and actuality (energeia/entelecheia: the realization or fulfillment of that capacity)—as reinterpreted in existentialism by thinkers like Søren Kierkegaard and Martin Heidegger.

Blocked Transition from Potentiality to Actuality

In one reading, anxiety arises when possibilities (potentiality) feel endless or overwhelming but lack a clear, concrete path ("ingress") to realization. The future looms as an abyss of freedom—full of "what could be"—yet without tangible ways to actualize choices. This echoes Kierkegaard's description in The Concept of Anxiety (1844), where anxiety is the "dizziness of freedom": we confront infinite possibilities, but the act of choosing (leaping into actuality) induces dread because it involves responsibility and the forfeiture of alternatives. Freedom's "possibility of possibility" tempts us, but stepping into concrete action feels paralyzing.

Stagnant or Closed-Off Present

Alternatively, the present reality (actuality) feels rigid, suffocating, or devoid of further openness—no room for growth, change, or new possibilities. Life becomes mechanical or inauthentic, trapped in routine without horizon for transformation. Heidegger in Being and Time (1927) describes anxiety (Angst) as a mood that strips away everyday significance, revealing the world as "uncanny" and Dasein (human existence) as "thrown" into a finite existence. Here, actuality confronts its limits (e.g., death as the ultimate non-relational potentiality), closing off illusory openness while paradoxically disclosing authentic potential for resolute being.

The Dual Torment of Anxiety

Anxiety, then, is the torment of this disrupted flow: either boundless potentiality frozen without entry into the real, or a suffocating actuality sealed off from possibility. Yet existentialists see it positively—disruptive but revelatory. It individualizes us, pulling us from conformist "they-self" absorption (Heidegger) or unreflective immediacy, toward authentic selfhood where we own our freedom and finitude.
