adequately. “Historical knowledge may ‘reveal,’ point to, give the locus of
‘origins,’” Randall argues, “but it does not ‘explain’ them.”

In short,
identifying a thing’s origins is no substitute for understanding its nature.
The genetic method of learning about a thing through its history is not a
general method for understanding all kinds of things.
It is, however, indispensable for understanding some things. There are some
things the nature of which is to develop. As F. J. E. Woodbridge puts it, “the
nature of a thing may be progressive. Time may enter into its substance.”
19
Though the study of a thing’s genesis is not a general method for understanding
all things, it is anindispensablemethodforthestudyofthingsthenatureof
which is to develop. Consider a seed.
20
What is involved in understanding what
a seed is and why it is as it is? In one sense, of course, we understand a seed once
we have analyzed its chemical makeup – once we have identified its physical
structures and determined the materials out of which those structures are
composed. After all, there is nothing “more” to the seed than its physical
makeup. Everything that will ever happen to the seed is a function of its initial
chemical composition. The seed ’s chemical propert ies act as a set of “passive
powers,”“boundaries beyond which the operations of the seed’s processes of
growth cannot go.”
21
And we can analyze this chemical constitution “in
isolation,”
22
without knowing what will later happen to the seed as it turns
into a plant. In one sense, then, we know what the seed is, and why it is as it is,
when we have exhaustively enumerated its chemical properties.
It seems clear, however, that someone who understood the seed solely in this
way would be missing something. She would have a complete snapshot of the
seed’s passive powers. But she would be missing out on the most interesting
aspect of the seed: an understanding of what these powers can do. She would be
able to enumerate the seed’s passive powers, but she would not know how they
exhibit themselves in the seed’s processe s of growth. We cannot learn this from
an analysis of the passive powers themselves, because these powers manifest
themselves only in interaction with other factors. As Randall puts it:
The specific chemical structure is essential …, but it is not the only factor essential.
Other factors are needed to set those factors in operation, to serve as stimuli or
“active” powers. The soil, moisture, and sunlight interact with the seed as efficient
causes or dynamic factors. They are selective of the powers of that constitution,
determining which of them shall be realized within the limits set.
