bringing it into a set of aleatory relations with the exterior, the more
deterritorialized it is. That is why degrees of development must be under-
stood relatively, and as a function of differential speeds, relations, and
rates. Deterritorialization must be thought of as a perfectly positive power
that has degrees and thresholds (epistrata), is always relative, and has
reterritorialization as its flipside or complement. An organism that is
deterritorialized in relation to the exterior necessarily reterritorializes on
its interior milieus. A given presumed fragment of embryo is deterrito-
rialized when it changes thresholds or gradients, but is assigned a new role
by the new surroundings. Local movements are alterations. Cellular migra-
tion, stretching, invagination, folding are examples of this. Every voyage is
intensive, and occurs in relation to thresholds of intensity between which it
evolves or that it crosses. One travels by intensity; displacements and
spatial figures depend on intensive thresholds of nomadic deterritoriali-
zation (and thus on differential relations) that simultaneously define com-
plementary, sedentary reterritorializations. Every stratum operates this
way: by grasping in its pincers a maximum number of intensities or inten-
sive particles over which it spreads its forms and substances, constituting
determinate gradients and thresholds of resonance (deterritorialization on
a stratum always occurs in relation to a complementary reterrito-
rialization).

As long as preestablished forms were compared to predetermined
degrees, all one could do was affirm their irreducibility, and there was no
way of judging possible communication between the two factors. But we
see now that forms depend on codes in the parastrata and plunge into pro-
cesses of decoding or drift and that degrees themselves are caught up in
movements of intensive territorialization and reterritorialization. There is
no simple correspondence between codes and territorialities on the one
hand and decodings and deterritorialization on the other: on the contrary,
a code may be a deterritorialization and a reterritorialization a decoding.
Wide gaps separate code and territoriality. The two factors nevertheless
have the same "subject" in a stratum: it is populations that are deter-
ritorialized and reterritorialized, and also coded and decoded. In addition,
these factors communicate or interlace in the milieus.
On the one hand, modifications of a code have an aleatory cause in the
milieu of exteriority, and it is their effects on the interior milieus, their
compatibility with them, that decide whether they will be popularized.
Deterritorializations and reterritorializations do not bring about the mod-
ifications; they do, however, strictly determine their selection. On the other
hand, every modification has an associated milieu that in turn entails a
certain deterritorialization in relation to the milieu of exteriority and a cer-
tain reterritorialization on intermediate or interior milieus. Perceptions

and actions in an associated milieu, even those on a molecular level, con-
struct or produce
territorial signs (indexes). This is especially true of an ani-
mal world, which is constituted, marked off by signs that divide it into
zones (of shelter, hunting, neutrality, etc.), mobilize special organs, and
correspond to fragments of code; this is so even at the margin of decoding
inherent in the code. Even the domain of learning is defined by the code, or
prescribed by it. But indexes or territorial signs are inseparable from a dou-
ble movement. Since the associated milieu always confronts a milieu of
exteriority with which the animal is engaged and in which it takes neces-
sary risks, a line of flight must be preserved to enable the animal to regain
its associated milieu when danger appears (for example, the bull's line of
flight in the arena, which it uses to regain the turf it has chosen).
18
A second
kind of line of flight arises when the associated milieu is rocked by blows
from the exterior, forcing the animal to abandon it and strike up an associa-
tion with new portions of exteriority, this time leaning on its interior
milieus like fragile crutches. When the seas dried, the primitive Fish left its
associated milieu to explore land, forced to "stand on its own legs," now
carrying water only on the inside, in the amniotic membranes protecting
the embryo. In one way or the other, the animal is more a fleer than a
fighter, but its flights are also conquests, creations. Territorialities, then,
are shot through with lines of flight testifying to the presence within them
of movements of deterritorialization and reterritorialization. In a certain
sense, they are secondary. They would be nothing without these move-
ments that deposit them. In short, the epistrata and parastrata are continu-
ally moving, sliding, shifting, and changing on the Ecumenon or unity of
composition of a stratum; some are swept away by lines of flight and move-
ments of deterritorialization, others by processes of decoding or drift, but
they all communicate at the intersection of the milieus. The strata are con-
tinually being shaken by phenomena of cracking and rupture, either at the
level of the substrata that furnish the materials (a prebiotic soup, a
prechemical soup ...), at the level of the accumulating epistrata, or at the
level of the abutting parastrata: everywhere there arise simultaneous accel-
erations and blockages, comparative speeds, differences in deterrito-
rialization creating relative fields of reterritorialization.
These relative movements should most assuredly not be confused with
the possibility of absolute deterritorialization, an absolute line of flight,
absolute drift. The former are stratic or interstratic, whereas the latter con-
cern the plane of consistency and its destratification (its "combustion," as
Geoffroy would say). There is no doubt that mad physical particles crash
through the strata as they accelerate, leaving minimal trace of their pas-
sage, escaping spatiotemporal and even existential coordinates as they
tend toward a state of absolute deterritorialization, the state of unformed
