Lonergan’s
Interpretation of Scientific and Philosophic Method
Philosophic Method
Whitehead’s analysis of scientific
method and its fundamental assumptions grew out of a long career in the
philosophy of science and a consistent concern to ground science by
illustrating the reasonableness of its method and its assumptions.
Bernard Lonergan’s analysis of empirical scientific method grew out of
a quite different context. In the course of his lengthy study of
philosophy, Lonergan became interested in Aquinas’ views on
understanding and, as a result of his research, concluded that for
Aquinas the key to cognitional theory was to be found in acts of
understanding, not in concepts.
Lonergan’s studies of
Aquinas on this topic were published in a series of five articles
entitled “The Concept of Verbum in the Writings of St. Thomas
Aquinas,” Theological Studies 7 (1946): 349-392; 8 (1947): 35-79;
404-444; 10 (1949): 3-40; 359-393. These were subsequently reprinted as
Bernard J. Lonergan, Verbum: Word and Idea in Aquinas, ed. David
B. Burrell (Notre Dame, Ind.: University of Notre Dame Press, 1967).
Immediately after this extended study of Aquinas, Lonergan began work on
,his major inquiry into human understanding, Insight.
Bernard J. F. Lonergan,
Insight: A Study of Human Understanding (New York: Philosophical
Library, 1957; revised edition, 1958). Hereafter cited as Insight.
According to his own testimony, the analysis of human understanding
contained in Insight was intended to serve as a groundwork or
foundation for a study of method in theology.
See “An Interview with
Fr. Bernard Lonergan, S.J.,” in Bernard J. F. Lonergan, A Second
Collection, ed. William F. J. Ryan and Bernard J. Tyrrell
(Philadelphia: The Westminster Press, 1974), p. 213; and “Insight
Revisited,” ibid., p. 268. The latter article contains an
autobiographical account of Lonergan’s studies in philosophy and
theology which led to the writing of Insight; see ibid.,
pp. 263-268. This collection of articles will hereafter be cited as
Second Collection. Insight was the groundwork for Bernard J.
F. Lonergan, Method in Theology (New York: Herder and Herder,
1972; 2nd [corrected] edition 1973). Hereafter cited as Method.
Thus it was not an immediate interest in science itself which provoked
Lonergan’s analysis of empirical scientific method, but rather a desire
to arrive at a formulation of theological method for the modern period
by means of a study of the structure and dynamic of human understanding
in general.
Lonergan himself, in the
Introduction to Insight, has explained why he undertook a lengthy
analysis of empirical scientific method, and he offers three reasons.
First, Lonergan states, if his account of the levels of consciousness
is to be intelligible, the different kinds of activity that constitute
the successive levels of consciousness must be clearly stated. For this
task he chose to work with illustrations from the mathematical and
empirical sciences because they offer the clearest, most precise, and
most successful examples of the use of insight and its structural
pattern to govern the method of inquiry.
[Insight, p. xx.]
A second reason for dealing with
mathematics and mathematical physics so extensively is to be found in
“the significance of the transition from the old mechanism to relativity
and from the old determinism to statistical laws.”
[Ibid., p. xxi.] This involves a complex of three
related issues. First, Lonergan notes that the experiment which is
modern science began in Galileo with “the blending of scientific
principles and philosophic assumptions,” but has ended in our day “with
their sharp segregation.”
[Ibid.]
Hence today we are faced with a “duality” in our knowledge, an apparent
dichotomy between the highly precise and successful empirical sciences
on the one hand, and the suspect mode of philosophic thought on the
other. Yet the developments in physics in the twentieth century offer
hope for a resolution of this “duality,” and Lonergan is convinced that
an analysis of the structure and dynamic of human knowing will yield a
philosophy capable of unifying and organizing all departments of
knowledge, resulting in a metaphysics that unifies and organizes all
that is known.
See Ibid., p.
xi, xxviii-xxix, for introductory statements of this conviction. I will
address this issue in some detail below.
In other words, he is convinced that by a careful examination and
analysis of the nature of our knowing, we can arrive at an understanding
of knowing that will dissolve the apparent duality in our knowledge. It
will accomplish this by demonstrating the unity of “scientific
principles” and “philosophic assumption,” even while recognizing and
respecting the proper reason for their “sharp segregation” in our time
(namely, the legitimate autonomy of the empirical sciences).
Involved in the demonstration of the
unity of “scientific principles” and “philosophic assumptions” are two
specific characteristics of the transition from the “old” to the “new”
physics. The transition from mechanism to relativity marks the
abandonment of naive realism and the adoption of critical realism as the
dominant scientific interpretation of reality. In modern physics, the
real is not the “already out there now,” and objectivity does not
consist in “taking a good look” at the “already-out-there-now-real.”
For the technical
meaning of the phrase “already out there now real” see ibid., p.
251. Perhaps the best summary of this is to be found in Lonergan’s
treatment of empiricism, ibid., pp. 411-416. For a fuller
treatment consult the Index, ibid., entries “Real: ‘Already out
there now’”; “Knowing-Objectivity-Reality-Truth”; “Knowing and looking”;
“Objectivity: Extroversion as model of”; “Objectivity and imaginable.”
It ought to be noted
that there is a correlation between Lonergan’s epistemological critique
of naïve realism and Whitehead’s critique of the classical notion of
“simple location” and his attack on the “sensationalist” basis of
positivistic epistemology. I will return ‘to this correlation later in
my study.
The real in modern physics is not the sensible, not the imaginable, but
the intelligible, that which is to be verified in the data; and
objectivity consists not in “taking a good look at the
already-out-there-now-real,” but in faithfully submitting oneself to the
discipline of empirical method in the conduct of scientific inquiry. Lonergan
will attempt to demonstrate that this modern understanding of the real
and of objectivity springs from the very structure and dynamic of
knowing and is an illustration of the basic unity of scientific
principles and philosophic assumptions. One other characteristic of the
transition from the “old” to the “new” physics is also of great
importance in Lonergan’s view, the transition “from the old determinism
to statistical laws.” This marks an abandonment of dogmatic certitude
and, instead, a dependence on probable judgments as the basis of
scientific knowledge. Our knowing in science, in common sense, and in
philosophy alike, Lonergan will argue, rests on the making of probable
judgments, not on any intuitive and certain grasp of the true and the
real. The process of our knowing does not lead us to absolute
certitudes grasped once and for all, but by making probable judgments we
guide ourselves along an asymptotic approach to the truth. For all
these reasons, the evidence about human knowing contained in the
transition to modern physics must be considered.
But there is yet a third reason for
making an extensive analysis of empirical scientific method. Lonergan’s
purpose is to come to an understanding of all human understanding, and
by means of this to arrive at “a basic understanding of all that can be
understood.”
[Ibid., p.
xxviii.]
As he states his programme: “Thoroughly understand what it is to
understand, and not only will you understand the broad lines of all
there is to be understood but also will you possess a fixed base, an
invariant pattern, opening upon all further developments of
understanding.”
[Ibid. The entire sentence is italicized in Lonergan’s text.]
Analysis of empirical scientific method, then, will well serve
Lonergan’s purpose.
For such thought is methodical and
the scientist pins his faith, not on this or that scientific system or
conclusion, but on the validity of scientific method itself. But what
ultimately is the nature and ground of method but a reflective grasp and
specialized application of the object of our inquiry, namely, of the
dynamic structure immanent and recurrently operative in human
cognitional activity? It follows that empirical science as methodical
not merely offers a clue for the discovery but also exhibits concrete
instances for the examination of the larger, multiform dynamism that we
are seeking to explore.
[Ibid., p. xxi-xxii.]
Lonergan is interested not in the particular content of scientific
theories or conclusions, but in the structural and dynamic features of
empirical method which are illustrations of the structure and dynamism
of human understanding at work.
Thus for three reasons, Lonergan
begins his study of human understanding with an extensive analysis of
empirical scientific method: for clarity and precision in stating the
kinds of activity that constitute the successive levels of
consciousness; because the transition to modern physics contains a good
deal of evidence about the nature of human knowing; and because the
faith of the scientist is based on the validity of the method the
scientist uses to pursue understanding, and that method is a specialized
application of the same dynamic structure that underlies and guides all
human knowing.
