Rather, it is concerned with locating the precise boundary between the banal and the extraordinary, between routine and violence, between complacency and courage.
In all but a few cases, speciation is a long and gradual process such that there is no principled way to draw a precise boundary between one species and the next.
The classic Sorites, or 'heap argument', seeks to show that even 10,000 grains do not make a heap, on the ground that (a) three grains do not, and (b) the addition of one grain could never be enough to turn a non-heap into a heap: however often a further grain is added, no precise boundary between non-heap and heap is ever found.
Ultimately, the garden wall occupies the precise boundary between nature and culture and is well-suited to Crystal Bridges Southh Lawn, situated along one of the beautiful nature trails that traverse the Museum's 120-acre grounds.
Pragmatically speaking, however, the precise boundary between a reversible alteration in homeostasis and an irreversible loss of cellular activities appears to be virtually impossible to identify.
Because precise boundary between other subgroups of the AH neurons was not always evident, neurons outside the ON and DL were grouped as "other AH" (OAH, Figure 2a,d).
The boundary between segment 2 and segment 3 on Bd4 lies between Bradi4g38980 and Bradi4g39020; more genetically mapped markers are required to determine the precise boundary between segments 1 & 2, and any smaller rearrangements that might have occurred within each deletion bin.
The precise boundary between normal and abnormal phenotypes must be chosen by us, based on our observation of symptoms and assessments of harmful dysfunction; it is up to us to determine when an individual's suffering rises to the level of warranting treatment.
However, in most cases precise boundaries are formed between different cell types without early compartmentalization.
