a source of despair, has been a wellspring of wisdom in numerous philosophical and spiritual
traditions.
In the Stoic tradition, for example, the contemplation of death is not seen as morbid, but
rather to live a life of virtue and purpose. (Menzies y Whittle 2022) Marcus Aurelius and Seneca both
advocated for a mindful awareness of death, seeing it as an impetus to prioritize what truly matters—
moral integrity, inner peace, and a life aligned with nature. The Stoic approach emphasizes that by
contemplating death, we can better appreciate the present moment, cultivate gratitude, and avoid
distractions that detract from a meaningful existence. In existentialist thought, death occupies a
similarly crucial role, though the approach is more focused on individual freedom and the burden of
responsibility. Thinkers like Jean-Paul Sartre and Martin Heidegger argue that the awareness of
death—what Heidegger terms "being-toward-death"—serves as a defining aspect of human existence.
Death, in this context, is not just an end, but a horizon that gives shape and urgency to our lives.
Confronting our mortality forces us to acknowledge our freedom to choose and the responsibility that
comes with it, urging us to live authentically and embrace the uncertainty of life. Death, thus, becomes
the very condition that allows life to have meaning and significance. Furthermore, in various spiritual
traditions, the awareness of mortality is not only an existential realization but also a spiritual
teaching. Buddhism, for instance, presents the contemplation of death to cultivate impermanence
and detachment, fostering a deeper understanding of the transient nature of all phenomena. This
understanding is said to lead to wisdom and compassion, as individuals recognize the shared fate of
all beings and are motivated to act with kindness and mindfulness.
Hans Jonas proposes an ontology that goes beyond death, not only for human beings but for
all organisms, in which their existence depends on the actions that sustain it. The German
philosopher states that organisms are beings whose existence relies on their own actions. This means
that their being is not something they possess in a stable way but is in constant becoming, generated
by what they do. The being of an organism is, therefore, a continuous extension of its actions, and it
only exists if these actions are carried out. In this way, ceasing to act also implies ceasing to be.
Furthermore, the ability to act does not depend solely on the organisms but also on the environment,
which can either support or hinder them. Thus, life is intrinsically linked to death, as the possibility
of ceasing to act is present from the very beginning of life. (Jonas 2012, 65)
In the previous lines, we encounter an ontological understanding of the human being that is
both insightful and pragmatically significant. A key ontological feature of any organism is its drive to
maintain life, as its very survival is contingent upon this act. If we were to extend this ontological
concept into the biological domain, we would be referring to metabolism, the fundamental set of
processes by which an organism converts energy to sustain its vital functions. Metabolism is essential
for life, as it governs growth, reproduction, and the maintenance of homeostasis, thereby ensuring
the organism's continued existence. The human being, as an organism, depends on actions such as
feeding and regulation to stay alive, which implies its ontological fragility: if it stops performing these
actions, it loses its being. According to Jonas, this dependency not only falls on the organism but also
on the environment, which determines whether it can continue to exist. Thus, fragility and
vulnerability are inherent to organisms, evident in their dependence on external resources like food,
water, and air. The lack of these resources can lead to illness or death, highlighting the precariousness
of our biological existence.
All organisms are in continuous interaction with their environment, a relationship essential
for their survival as it provides vital resources such as food, water, and shelter. However, this
environment also presents potential threats— predators, harsh weather conditions, diseases—that
can undermine the organism’s survival and well-being, exposing its inherent fragility and
vulnerability. Furthermore, the environment is dynamic and constantly evolving, requiring
organisms to adapt to survive. Yet, adaptation is not instantaneous; it demands both time and
resources, and when environmental changes surpass an organism’s ability to adapt, its vulnerability
increases, potentially jeopardizing its existence. Biological complexity increases the ontological
vulnerability of organisms, including human beings, as any disturbance in their interconnected
systems can affect their integrity. Moreover, human vulnerability extends to social and economic
structures, which, while critical for well-being, are fragile and can be impacted by external factors
such as wars or crises. Thus, human well-being is closely linked to the stability of social institutions.
These are traits that affect the fragility of the flesh; the body, particularly the aging body,
makes this ontological characteristic of all living beings, including humans, evident. This ontological
fragility can be overwhelming; it can generate fear at the possibility that our existence may end at any
