Nature, Environment, and Human Being:
Hans Jonas on the Principle of Responsibility1

SHINAGAWA, Tetsuhiko
1 Nature as Environment
A kind of tension is included in the theme "Nature as Environment", on which we
hold this symposium today. While the idea of nature means the universe including
everything

and is therefore never relativistic, the idea of environment presupposes

an entity which stands at the center of it. We call this entity a subject of environment.
Environment is only the perspective of its subject. The former is a piece of nature cut
down relative to the interest of the latter. Uexküll, a biologist who produced the ideaof environment (Umwelt), describes how the environment of mites is shrunk according
to the needs for their survival (1). The environment of human beings as living things
is no more than a more or less shrunk piece of nature.
We, human beings, however, get a possibility to regard the whole nature as ourenvironment. When since 1920s philosophical anthropology has began to recapturescientific knowledge of human beings as living things into philosophy, the idea ofenvironment has not only belonged to biology, but also to philosophy. Plessner, one offounders of philosophical anthropology, asserts that the specific nature of humanbeings consists in their capacity of detaching themselves from their bodies. Plessner
called this characteristic excentricity. Human beings can objectify their bodies, theirenvironment around them, and the relation between it and themselves (2). Scheler
also points out the same condition expressing that human being is opened to theworld (3).
The capacity to objectify the own environment leads to the capacity to operate andarrange it voluntarily. The arrangement of it by means of sciences and technology byhuman beings is going ahead globally and is eventually changing the form of life
irreversibly. It has become real that the whole nature is regarded as the environmentof human beings interactive to their activities.
Yet the environment of human beings overlaps ones of other living beings because ofThis article was originally written in Japanese and published in the Arche

original title was “Shizen, Kankyo, Ningen – Hans Jonas Sekinin toiu Genri nituite”.
11the unity of the nature. The arrangement of environment by human beings cannot but
influence the survival of each species, which have its own environment as subject.
Therefore an ethical problem occurs if the subject in question should be respected.
Now what do we think should be respected? After all, is the destruction ofenvironment wrong because it harms human beings? Or is it wrong because it harms
all subjects of environment besides human beings?

If you prefer the former question

to the latter, you would support anthropocentrism, while if otherwise, you would
support non-anthropocentrism or biocentrism.
Leopold's land ethic and Naess' deep ecology appeal to biocentrism. They assert that
ecosystem is maintained by interdependence of various kinds of living things.
Therefore not only mankind but also any species of living thing should be equallyrespected as an essential member of the ecosystem and the varieties as well as
symbiosis of various kinds of species should be defended.
Anthropocentrism criticizes biocentrism. At first, a transcendent criticism is thathuman beings are originally anti-natural entities. Or pursuing long-range interest of
human beings, they can defend the existence of various kinds of living things andtheir environments effectively (7). One type of this argument is called stewardshipenvironmental ethic, because it regards human beings as the steward whom the God
the nature to (8). Secondly comes an immanent criticism： we are compelled to discard
biocentrism and think anthropocentrically. The reason is that only human beings cantake over the moral task, although biocentrism recognizes human beings and otherliving things equally as a member of moral community (9) (10).
But this immanent criticism commits an error, because it fails to distinguish humanbeings as subjects of interest from ones as moral agents. For it is not excluded inprinciple that human beings as moral agents may choose the norms of action against
their interest (11). The point of issue of biocentrism does not consisted in it, but rather
in the failure to recognize the specific status of human beings as moral agents because
it emphasizes the equality of mankind and other species from the moral point of view.
It can no longer take a symmetrical position to other living things because it has
gotten the capacity to arrange its environment. So mankind should be possiblyaccused relative to its capacity.
Should we then support anthropocentrism? But can the interest and desire of humanbeings be entitled to be the ground of ethic?

This is criticized by biocentrism.

Biocentrism itself, however, may be criticized likewise, so long as it only enlarges thescope of subject of interest to cover non-human living things. Indeed they may desire
to continue their lives. But if we say "Protect ecosystem, if you desire to go on to live",2

this imperative does not rely -- a la Kant -- on morality, but on cleverness. Therefore if
the survival of mankind and the existence of life or nature should be respected fromthe authentic ethical point of view, other grounds will be required than the desire ofhuman beings (anthropocentrism) or the desire of living things (biocentrism).
Can cultural regionalism produce good grounds? The idea of environment iscombined with regional specialty because of its original meaning of 'surroundings'.
One of claims of deep ecology is to maintain the specialty of each region so that man
could preserve the variety of ecosystem in the whole nature. Further the nature in agiven region is closely intertwined with the life of human beings there. We can read
Watuji's philosophy of Fudo (milieu) as an approach to defend both nature and culture
because of their unfolded intertwinement. After Watuji has dwelled on the condition of
the milieu of Japan, he advocates the love for Japanese milieu suddenly (12). Here
Tosaka finds Watuji's disgust at Marxism's day in the beginnings of the Showa period
in Japan (13). But it is plausible that Watuji is to go on for such a love after all,because he emphasizes norms appropriate to the specialty of the milieu. Nonetheless
he would not claim cultural relativism. The reason is that he regards the specialty of
milieu as expression of the generality of humanity. Thus the arguments for specialtyof the regional environment presuppose doubtlessly the existence of the whole natureand the survival of mankind. Yet should not even this presupposition be founded at
first?
The foundation of survival of mankind and existence of nature -- these twocommands seem to be extravagant and indifferent to each other. However so long as
human beings can objectify the nature as their environment, it is up to human
freedom whether it will be destroyed or conserved and, accordingly, whether mankind
will perish or not. Therefore the foundation of mankind and the existence of nature orlife are most fundamental and are yoked to each other. By the way the permissibilityof perishment of mankind has already been questioned in philosophy. This question
appeared in a field of vision, when Kant inquired about permissibility of suicide in thelight of the general moral law.
Now I will take up Hans Jonas' Principle of Responsibility which investigated thefoundation of survival of mankind and existence of nature. (The numbers mentioned
in [ ] indicate the page of references cited from Hans Jonas, Das Prinzip

Verantwortung, Suhrkamp Taschenbuch, 1984.)
2 Hans Jonas' Principle of Responsibility
Ethics has dealt with action on the basis of face-to-face relation. And it has expected3that the good for the present human generations would be also applied to the future
ones. Therefore its scope does not go beyond the present, even if it could acquire
universal validity among the present moral agents. Owing to sciences and technology,
however, human activities can influence the far future and threaten to alter the global
environment irreversibly. It is Jonas’ principle of responsibility that evolves aforthcoming ethic considering the influence of human activities upon future and thewhole nature [224-226].
Entities which we can be responsible for meet the following three conditions [166,175]. At first the entities does not belong to me. Secondly they are threatened tovanish in time, i.e. they are vulnerable. Thirdly it relies upon my power whether they
will continue to be or vanish actually. Now we should bear two points in mind. (i)Jonas’ concept of responsibility means one for the continued existence, i.e. future,
while man usually applies the concept only to our previous action. (ii) His concept of
responsibility is based upon asymmetry of power so that it is established in unequaland nonreciprocal relations as contrast with the concepts of justice and right.
Jonas finds the paradigm of responsibility in one for newborns [235]. Only breathing,
they impose irrefutably obligations to care for them upon us. Why should we care forthem? We do not always love them. The reason is not that they have potentiality to beperson afterwards. Some bioethicists such as Tooley disclaim the right to live of
newborn (14). But, according to Jonas, we do not see newborns, so long as we see themas aggregate of cells. “Ihn [Säugling] bekommt der analytische Blick desmathematischen Physikers gar nicht zu Gesicht, sondern mit Absicht nur einenäußersten Rand seine im übrigen abgeblendeten Wirkrichkeit. Und selbstverständlichverlangt noch die hellste Sichtbarkeit den Gebrauch des Sehvermögens, für das sie daist. An dieses richtete sich unser 》Sieh hin und du weißt《“[236]. If I do not care forthe newborn, what will happen upon it? [391]. This feeling imposes responsibility for
it upon me.
However I could reject to care for it. Jonas deliberately did not say ‘irresistibly‘, but‘irrefutably’. Indeed human beings feel responsibility, but they do not necessarily
fulfill it. Even if they fail to do it, they are nevertheless ethical beings, because they
do aware of responsibility. The foundation of moral is found no other than here. The
reason for human beings to continue to be does neither lie in human desire nor inright to live nor in reason: it lies simply in the idea of human beings as foundation of
ethics. They are always and already responsible and at once it is not settled yet
whether they fulfill their responsibility in fact. This temporal structure of “being
already and not yet” accompanies with the idea of human beings forever. Jonas4

vehemently rejects the utopian thought which expects the arrival of ideal humanbeings without this ambiguity.
However ecological crisis owing to human beings threatens the continued existenceof mankind no less than one of the other living creatures. Jonas’ argument is asfollows:

the continued existence of mankind is hardly sustained, if we reckon up thebalance sheet whether it is delightful or awful for the whole world. Independent of thebalance sheet, nevertheless, mankind should continue to be. The reason is that thefirst responsibility is for possibility for responsibility in general to be [186]. It is up to
the present generation how man deals with ecological crisis. Because it has theexistence of future generations in its hands, it is responsible for them.
Thus Jonas has established care for future, which is one of necessary conditions for a
forthcoming ethic. But there is another condition for it: it should care for the nature.
If man only realizes our description so far, man might possibly think that the nature
should be respected as instrument for the continued existence of mankind. We must
add Jonas’ philosophy of nature which requires that the nature should be respected initself.
Human action accompanies with intentional purpose. However purpose is found not
only in conscious beings, but also in any function of organisms: for example, stomach
has a function to digest. Each part of body contributes the purpose for the organism tolive [130]. When has this ability to have purpose appeared in history? Has it appeared
emergently from substances void of purpose by mutation and natural selection? Jonas
does not adopt such an explanation. If we reduced to substances void of purpose, wewould commit assumptio non probata because it must presuppose that there isoriginally no purpose in the nature. According to Jonas, we can infer that naturalprocess ensures potentiality of existence of purpose from the obvious fact ofappearance organism in the nature [136-138] (15).
Now the good is no other than fulfillment of purpose of purposeful entities [154].
Purpose requires that they should be what they are as realization of their purpose. It
also commands the other entities not to prevent its realization [234]. Indeed purposeof one organism might have instrumental value, be neutral or against for otherorganisms. But while value is only relevant to a specific entity, the good is not relative[160]. If value for human beings were the good itself, the good would be created byhuman intention so that it could not restrict human will. Jonas supposed in thenature the good itself which does not rely on evaluation by human beings.
Independent of human desire, therefore, he could establish the responsibility which
requires that human beings should abstain from preventing purposes of other species,

5which are threatened by human will and power [185, 232].
I have summarized Jonas’ principle of responsibility and his philosophy of nature so
far [245-246] (16). Contrary to anthropocentrism, he does not justify human desire.
And contrary to biocentrism, he makes clear the special status of human beings as
moral agents belonging to the nature. Could we now get a forthcoming ethic which is
fully founded upon the principle of responsibility? However Jonas has been criticizedby discourse ethics, which is very keen of the problem of foundation. Let us deal withthis criticism at last.
3 The criticism upon Jonas by discourse ethics
Proponents of discourse ethics claim the deficiency of Jonas’ foundation, because it
only appeals to intuition. Jonas refers to the situation of newborns as paradigm ofresponsibility and claims “See, then you know it.” How could he deal with someone
who does not feel responsibility to care for it at all? Jonas cannot but shut out
refutation, as Hume finished his argument against the people who denied sympathy.
On the contrary, discourse ethics claims that it can deal with such a refutation. A
community of communication has been already constructed by responsible agents. It
is the necessary presupposition which man could not go far beyond, because we cannot
but appeal to this community whenever we would claim the recognition and possible
acceptance of our arguments. In the community it would be discussed whether the
responsibility for newborns should be established. Once it had been established in theprocess of discourse, someone who discards his responsibility would be in conflict
between himself and the consensus which he had participated in. This performative
self-contradiction argument compels him to fulfill his obligation. On the contrary, inthe principle of responsibility someone who cannot ‘see’ his obligation to care for the
newborn cannot be compelled to fulfill it. As Werner points it out, there is no court of
instance where the moral agent should be questioned no other than his intuition
towards objects he might be responsible for (17).
Discourse ethics approves Jonas’ appeal to continue the existence of mankind and tocare for environment. According to discourse ethics, community of communication is
the foundation of ethics. Following generations of mankind must be commanded,because they are to be forthcoming members of the community of communication andit should be ensured. Care for environment is a necessary condition for it. And if
someone argues for care for nature now, his chance for it is ensured by discourse
ethics, because community of communication should be open to any argument.
Therefore the conflict between discourse ethics and Jonas does not consist in the6conclusion, but in the problem of foundation.
However I dare to say that Jonas has not only brought an intuitionalist foundation.
His argument could be based on referring to so-called performative self-contradiction.
Jonas’ question does not lie in a factual problem whether mankind can continue to be,
but an ethical problem whether it should do so. If man gave a negative answer to it,
man would deny the basis of ethics on which the question “should / should not” could
be raised: the negative answer would make the question as such nonsense. Thus wemust give the answer that mankind should continue to be. Therefore the existence of
responsibility is inevitably derived as the first responsibility.
But this type of argument appealing to performative self-contradiction can beapplied only to the approval of continued existence of mankind. It does not prescribe
what we should do to ensure to make mankind continue. Our actual activities would
be morally judged in community of communication and members of it would becommitted to the discourse. As told above, Jonas’ foundation is void of such efficiency.
Therefore it cannot give us a concrete diagnose. This is also criticized by discourse
ethics.
Man should not, however, fail to be aware that the continued existence of mankind in
the principle of responsibility corresponds to one of community of communication indiscourse ethics. The principle of responsibility builds up the base on which any ethic
can be established and makes sure our ethical attitude i.e. our ethical being above all.
According to discourse ethics, it would require to establish community ofcommunication. Which principle precedes in order to be ethical, the principle ofresponsibility or the principle of justice on which discourse ethics is based? Each party
would give different answer. But man should have it in mind: In discourse ethics man

calls and makes claim (Anspruch) and make a response to and is responsible for(Verantwortung) the members who are equal because of their reason or ability tocommunicate, while responsibility derives from asymmetry of power in Jonas.
Therefore discourse ethics cast a doubt on the responsibility in Jonas’ sense, because
it is sometimes called forth when man need not to respond, i.e. supererogation (18).
However the responsibility in such a sense makes us respond just to call from otherentities than us.
Now my argument which might be against the criticism from discourse ethics has
focused upon the continued existence of mankind so far. It might possibly mislead
readers to recapture the issue into affairs of human beings. Now I must refer to theother aspect of Jonas i.e. his philosophy of nature again.
However even proponents of Jonas would hesitate to abide by it. Could man conclude

7

that purpose exists objectively because life is not to be explained without purpose?
When Apel says that Jonas’ philosophy of nature is no other than dogmatism before
Kant, this criticism is justified under the framework of modern philosophy after Kant
(19). On the contrary, if we stand by Jonas, Kant seems to ascribe the obvious factthat organism is part of the nature because of its living body to the problem of humanrecognitive ability. Jonas’ philosophy of nature has been also criticized repeatedly as
naturalistic fallacy. On the contrary, according to Jonas, the modern philosophy is aversion of ontology or metaphysics that abstracts purpose, value and norms from thenature [92]. However this refute would entail that Jonas’ philosophy of nature is noless than an alternative or a version of metaphysics. By the way it should be referredthat Jonas tried coherently to argue without appeal to God at least in the Principle of

Responsibility, although it is natural that we expect his theological thought in the
background [90].
Care for the nature except human beings, i.e. a necessary condition for theforthcoming ethic is derived from this philosophy of the nature. Many critics claimthat care for the nature should be founded ethically against environmental crisis. But
it is hardly accepted within the framework of the orthodox modern ethical theories.
Anthropocentrism takes the nature for mere instrument. Discourse ethics ensures theopportunity to argue for care for the nature. But it requires someone who has ability
to communicate, i.e. human beings, to represent it. Man cannot find positive
motivation for it within discourse ethics. Needless to say, the nature stands initiallyout of community of communication. On the contrary, Jonas’ philosophy of nature
which finds ‘should’ in the nature could be a motive for introducing this outside into
debate.
However man might claim that biocentrism also could be a motive. For example,
Leopold’s land ethic respects each species as member essential to maintain ecosystem.
This respect is based on the principle of justice, according to which each species
should not proliferate beyond its due portion in the ecosystem. Therefore land ethic
could answer in principle to the question about the appropriate population of deer inthe given region. But it must presuppose how the ecosystem should be. On thecontrary, Jonas’ philosophy of nature goes far so that it tries to found that man could
conceive of ‘should’ in the nature in general.
4 Conclusion
Entities which we can be responsible for meet the following three conditions. At firstthe entities does not belong to me. Secondly they are threatened to vanish in time, i.e.

8they are vulnerable. Thirdly it relies upon my power whether they will continue to beor vanish actually. Care for future generations and care for the nature are requisite
for the forthcoming ethic. The principle of responsibility derives them from existenceor furthermore possible existence of other entities than us. Therefore it needs not tobe directly committed in the aporia whether rights could be entitled to the entities
that do not exist yet, while this enigma must be settled up by the approach whichfounds the continued existence of mankind in right of live of future generations. The
nature in the sense of the principle of responsibility is the outside of subject in thegiven environment as well as the nature as environment which it can influence upon.
Indeed as discourse ethics points out, this principle might sometimes command us
supererogation. But at once it can build up ethical attitude initially. Therefore Jonas
could open ethical thinking towards the outside of it, i.e. future generations and thenature. In this sense Jonas could indicate us an approach to the forthcoming ethic at
least.
