From Parmenides' ban on non-being and Laozi's fertile emptiness to Nāgārjuna's śūnyatā, Hegel's dialectic, Heidegger's dread, and the Kyoto School's absolute nothingness.
Is there such a thing as nothing — and why is there something rather than nothing at all?
'Nothing' looks like the emptiest of topics, yet it has haunted philosophy from its beginnings. Parmenides declared that non-being cannot even be thought or spoken, launching a Western suspicion of the void; the atomists needed empty space for their atoms to move; Leibniz turned the whole thing into the deepest of questions — why is there something rather than nothing? Eastern traditions took a strikingly different path, treating emptiness not as sheer absence but as fecund and even ultimate: the Daoist 'wu' that makes use possible, the Buddhist śūnyatā that empties things of intrinsic nature. Twentieth-century thinkers made nothingness existentially concrete — the anxiety in which the world as a whole slips away, or the nihilating freedom of consciousness. Reading these views together shows that 'nothing' is not one idea but a family of very different ones.
Pre-Socratic (Eleatic)
'Being is, and non-being is not' — what is not cannot exist, cannot be thought, and cannot be spoken of. Since there is no non-being, there can be no void, no coming-to-be, and no passing-away; reality is one, ungenerated, and changeless. This absolute ban on nothingness set the terms against which most later Western metaphysics defined itself.
On Nature (the poem), 'Way of Truth'.
Pre-Socratic (Atomism)
Against Parmenides, the atomists assert that the void — non-being — is as real as the 'full', the atoms. 'Nothing exists except atoms and empty space; everything else is opinion.' Motion, multiplicity, and change are possible precisely because there is empty space for indivisible atoms to move through, so nothingness, as void, is a genuine constituent of reality.
Atomist fragments (reported by Aristotle and Diogenes Laërtius).
Daoism
Emptiness (wu) is not mere lack but the source of usefulness and the ground of being: the hollow of a vessel, the space of a room, the hub's empty centre make the thing serviceable. Being (you) is born from non-being (wu), and the Dao works through emptiness and non-action. Here nothingness is fecund and generative, the very opposite of a barren negation.
Dao De Jing, chs. 11 and 40.
Madhyamaka Buddhism
All things are 'empty' (śūnya) of intrinsic, independent nature: they exist only in dependent origination, not in themselves. Emptiness, though, is not a nihilistic void but the very truth that makes change and causation possible, and it too is empty (the 'emptiness of emptiness'). To grasp it wrongly — as sheer nothing or as a thing — is a dangerous error, 'like grasping a snake by the wrong end'.

Christian mysticism
Eckhart speaks of God as a 'nothing' beyond all created being — a divine darkness or desert that exceeds every name and category. The soul must become 'empty' and 'poor', detached from all things and even from its own will and images, to let the ungrounded Godhead be born within it. Here nothingness is the negation of all finite being that opens onto the divine.
German Sermons; treatise 'On Detachment'.
Rationalism
Leibniz poses the fundamental question of metaphysics: 'Why is there something rather than nothing? For nothing is simpler and easier than something.' By the principle of sufficient reason, the existence of a contingent world demands an explanation, which he finds in a necessary being, God, who chooses the best possible world. Nothingness is here the baseline against which the very fact of existence becomes astonishing and demands a reason.
'The Principles of Nature and Grace, Based on Reason' (1714).
German idealism
At the start of the Logic, pure Being — utterly indeterminate — turns out to be indistinguishable from pure Nothing, and their restless unity is Becoming. Nothing is thus not the mere opposite of being but a moment internal to it, the motor of dialectical development. Negation, the 'labour of the negative', drives the whole movement of thought and reality forward.
Science of Logic (1812–16), 'Being, Nothing, Becoming'.
Process philosophy / vitalism
The idea of absolute nothingness is a pseudo-idea: whenever we try to imagine 'nothing', we merely substitute one image for another and secretly keep a spectator present. There is always more, not less, in the notion of nothing than in that of something, so the question 'why is there something rather than nothing?' rests on a confusion. Reality is plenitude and creative duration, and the void is an illusion of the intellect.
Creative Evolution (1907), ch. 4.
Existential phenomenology
'Why are there beings at all instead of nothing?' is for Heidegger the fundamental question of metaphysics. The Nothing is not a mere logical negation but is disclosed in the mood of anxiety (Angst), where beings as a whole slip away and we confront the sheer fact of existence. The Nothing 'nihilates' and thereby first opens us to the wonder that beings are at all — it is intimately bound up with Being itself.

Existentialism
Consciousness (being-for-itself) is precisely a 'nothingness' at the heart of being: it is not a thing but the power to negate, to question, and to hold the world at a distance. It is through this nihilating power that absence, lack, and possibility enter the world — the 'not-being' of Pierre when I find the café empty. Human freedom is grounded in this nothingness by which we are never fully identical with what we are.

Kyoto School / Japanese philosophy
Bringing Zen and Mahāyāna emptiness into dialogue with Western philosophy, Nishida makes 'absolute nothingness' (zettai mu) the ultimate ground — a 'place' (basho) that is not a being among beings but the field in which all beings and oppositions arise. Unlike Western being-centred metaphysics, this nothingness is the self-negating source of reality and of the true self. It is prior to the subject–object split and encompasses it.
An Inquiry into the Good (1911); 'The Logic of Place' essays.
Kyoto School / Japanese philosophy
Nishitani argues that modern nihilism, in which everything loses meaning, must be passed through and overcome from within by moving to the standpoint of śūnyatā, absolute emptiness. This is not the nihilistic 'field of nihility' but a deeper ground where things are freed to be themselves in their 'suchness', beyond the grasping ego. Emptiness, fully realized, is thus the answer to nihilism rather than its final form.
