feld’s criticism simply points out the logical fault in reducing
the phenomenon of human thought to the molecules that sup-
port it as professed by Squire and Kandel in Memory: From
Mind to Molecules. The phenomena of our mind, according to
Greenfeld, cannot be explained by the existence of our brains
because, she asserts, the two processes seem to consist of dif-
ferent types of facts which are not translatable into one another
from the bottom up (Greenfeld, 2006). The laws of biology of
course, govern the structure and function of the brain, but the
biological characteristics of the brain are not positively deter-
minant in any instance of the mind. That is to say, it is not my
American brain that determines my English speaking thoughts
contemporary with the paradigms and trends of the 21st century,
but rather the activities of a mental process underdetermined by
all biological accounts.
This mental process could not occur without the human brain;
the brain serves as what Polanyi calls “boundary conditions”
for the activities of the mind (Polanyi, 1968). Remembering
that a condition is not a cause, however, the problem arises that
no quantity of data about the human brain itself explains the
qualities of the human mind. It is the inattention to this logical
confusion between condition and cause that has prevented the
subject of mind from being incorporated into the purview of
neuroscience. Greenfeld’s new approach, however, comes not
from negating the reductionist perspective, but rather from
reorienting the focus of inquiry toward the nature of the mind
and its connection to the biological brain.
The characteristic feature of the human mind is its symbolic
nature. To understand the novelty of this hypothesis, and to
make its formulation logical, one must recognize a symbol as
an arbitrary referent whose meaning is derived from the context
in which the symbol appears. Imagining symbols in this way
implies that any particular symbol’s meaning is always a matter
of interpretation—as context changes over time, so too may the
meaning of the symbol. This definition also implies that sym-
bols stand in qualitative contrast to signs, which always appear
in a one to one correspondence with their referent in the envi-
ronment and are timeless in their meaning.2 The biological
world consists of a dynamic material environment and organ-
isms to which the environment signifies. We know this from
Darwin’s framework which illustrates that the complexity of
signs increases with the complexity of the environment and
thus requires a proportionate level of adaptation for the survival
of a species. What Greenfeld reminds us in the case of the hu-
man mind is that an increase in complexity never explains a
break in continuity, and symbols constitute a reality of their
own kind in juxtaposition to the reality of signs. The human,
mental world is made up of symbols, facts that have only an
arbitrary connection to their referent in the material environ-
ment and have no necessary consequence for our biological
survival.
The primacy of symbols in human experience becomes im-
mediately apparent when one ponders the example of language,
our chief symbolic system. Words are symbols, that is, their
meaning is never absolute. They are the facts of a creative,
mental process and in every employment, our words must be
continually reinterpreted based on an ever-changing context.
Though this process is individual (i.e. language is always ma-
nipulated/symbols are always interpreted by one mind), words
most often are acquired from or given to other minds. No indi-
vidual is thought to be responsible for creating de novo all of
the words that they employ. Instead we use words and ideas
that are made available to us by our society and give them spe-
cific meaning by embedding them in the contexts of sentences
and scenes. It then follows through the example of language
that one can see Greenfeld’s second pivotal hypothesis about
the nature of human mind—it is a process made of up symbols
that are simultaneously individual and collective.
The symbolic mental process that is the mind is only active
in individuals but never exists in isolation from the common-
wealth of symbols that is shared across distances and genera-
tions. No mind is an island. The infant brain does not build a
mind from scratch relying solely on biological programming,
but instead develops with input from its particular symbolic
environment. We acquire our local language, are taught cus-
toms and slowly begin to participate in our uniquely human
ways of life whose variation across our species cannot be enu-
merated. The uniqueness of this process lies in the fact that,
unlike in any other species, it is indirect learning that occurs
when the younger members of our species individualize know-
ledge from the symbolic commonwealth. The symbolic nature
of the transmission of the human way of life therefore creates a
reality that is not possible in the world of signs; one in which
facts do not have to be experienced materially in order consti-
tute a reality for us.
Greenfeld insists that one must merely recognize the verity of
the mind’s existence (after all, she reminds us, it is the only certain
knowledge one can have) and then it can be operationalized as a
mental process governe d by the laws of symbol s. Greenfe ld states
that our mental reality is a uniquely human process made up of
symbols that, once externalized, become objective fact—i.e. they
exist. These facts are definable by the complex matrix of context
in which the symbol was e mployed. Like any dynamic biologi cal
process, the symbolic process is never static; despite this
dynamism, t he meaning of any symbol is di scoverable so long a s
there exists sufficient contextual evidence relevant to the subject
in question. This method of analysis can be imagined as analogous
to biological analysis on the cellular and molecular level. The
presence and effect of any particular cell or group of cells in a
biological system can only be detected and subsequently ex-
plained when sufficient contextual evidence about the subject is
empirically accessible in the system. Similar t o organic rea lity, the
number of forces that may be causal or effectual in the symbolic
environment is enormous and the discovery of new evidence
contributing to t he retroacti ve expl anation of a symbol i s alway s a
possibility. Therefore, in a manner parallel to that of the hard
sciences, authoritative explanations of facts in the symbolic
environment are the products of only the most logically consistent
and empirically supported chain of causality. One can consider the
analogy of Darwin’s finches as an even simpler example; the
distinct characteristics of a species’ beak become logically sig-
nificant only when analyzed in relationship to the finches’ en-
vironment, i.e. when analyzed in the framework of Darwin’s law.
When one accepts the reality of the mind as a symbolic process
and treats its phenomena as such, the facts of the mind (or, facts in
the symbolic reality) become subject to logical and empirical
analysis through the accumulation of circumstantia l evidence that
allows one to make hypotheses and refutations according to the
laws that govern the system. Symbols, as facts, can be explained
by discovering and analyzing the context that contributes to their
