Galileo, What Hast Thou Wrought?

2 Replies

Today we continue our study of how the statement, “I am a woman trapped in a man’s body” (Carl R. Trueman, The Rise and Triumph of the Modern Self, p. 19), came to be taken seriously by millions of intelligent people. The previous essay explained why no one before 1500 could have comprehended the modern dichotomy between the external appearances of such things as the male and female bodies and their internal reality. At the conclusion of that essay, I promised that in the next part “we will see how the architects of the scientific revolution—Galileo, Bacon, Descartes, et al.—destroyed confidence in the reality of forms and souls and replaced them with atoms, space, and machines. The appearances no longer reveal the reality of things. Creation is emptied of spiritual reality, meaning, purpose, moral law, and beauty, all of which are transferred to the inner subjective world of the human mind.” We begin that saga with Galileo Galilei.

Galileo Versus Aristotle

Students of nature before Galileo assumed that the way things appear to us reveals something about their inner reality and that the inner reality of things manifests itself truly in their external appearances. The meaning, purpose, beauty, moral law, and value we experience in our minds also exists in nature. The goal of Aristotelian science was understanding how all these qualities are embedded in the natures of the things themselves. However, by the time Galileo (1564-1642) came to maturity in the early seventeenth century, such thinkers as Francis Bacon (1561-1626), Rene Descartes (1596-1650), and Johannes Kepler (1571-1630) were already complaining that the doctrine of forms contributed nothing to our empirical understanding of things. Mysterious forms, whether they are real or not, cannot be clearly thought and have no value for making predictions, discovering laws, and creating technology. And for reasons I do not understand, achieving these goals had become the driving force of the emerging scientific revolution.

Galileo and the Mathematization of Nature

Galileo believed that applying mathematics to nature was the only way to achieve his practical goals. Numbers and mathematical operations are clear and simple, and when we see the value of a mathematical expression or equation, we become certain of its truth. To understand nature, argued Galileo, we should set aside questions about its mysterious inner nature, the ways it appears to us, and the way it makes us feel; these are irrelevant to achieving the goals of the new science. We will then be free to work out the mathematical laws of nature’s movements and transformations. At last, we can understand nature as clearly as we understand mathematics!

Unforeseen and Unintended Consequences

To modern ears, Galileo’s philosophy of science and his revisions to the scientific method sound familiar and innocent. Whatever Galileo’s intentions, however, his innovations produced a profound moral and religious revolution. For by limiting science to knowledge that can be expressed in mathematics, Galileo, Descartes, et al, broke decisively (1) with the traditional belief that things reveal their inner reality in their outward appearances, and (2) with the corresponding belief that the inner worlds of things in nature are intelligible and mindlike in a way similar to the inner world of the human mind.

The Distinction Between Primary and Secondary Qualities

Perhaps Galileo and other pioneers of the scientific revolution could have narrowed science to what can be understood in mathematical terms without postulating an alternative to Aristotle’s intelligible forms as the cause of the way things appear to us. But they did not exercise such restraint. Instead, they replaced Aristotle’s inner forms and souls with imperceptible material atoms or corpuscles, which possess only mathematically measurable properties: shape, movement, mass, velocity, etc. In ways Galileo and Descartes cannot explain, these material particles cause us to experience the world in a human way. By distinguishing primary qualities (material, mechanical, and mathematical) from secondary qualities (psychological, organic, and qualitative), they drove a wedge between the way human beings experience the world and the world as it is apart from human perception. The only bridge between the two is mathematics. Listen to Galileo, Descartes, and Locke drive this point home:

“To excite in us tastes, odors, and sounds I believe that nothing is required in external bodies except shapes, numbers, and slow or rapid movements. I think that if ears, tongues, and noses were removed, shapes and numbers and motions would remain, but not odors or tastes or sounds. The latter, I believe, are nothing more than names when separated from living beings, just as tickling and titillation are nothing but names in the absence of such things as noses and armpits” (The Assayer, 1623).

“The properties in external objects to which we apply terms light, color, smell, taste, sound, heat and cold—as well as other tactile qualities…are so far as we can see, simply various dispositions in the shapes, sizes, positions, and movements of their parts which make them able to set up various kinds of motions in our nerves which are required to produce all the various sensations in the soul” (Descartes, The Principles of Philosophy, 1644; Quoted in Cottingham, A Descartes Dictionary, p. 149).

“These I call original or primary qualities of body, which I think we may observe to produce simple ideas in us, viz. solidity, extension, figure, motion or rest, and number. Secondly, such qualities which in truth are nothing in objects themselves but powers to produce various sensations in us by their primary qualities, i.e. by bulk, figure, texture, and motion of their insensible parts, as colors, sounds, tastes, etc. These I call secondary qualities”(John Locke, Essay Concerning Human Understanding, 1698, II. 8)

Oh Galileo! What Hast Thou Wrought?

Galileo convinced the world that the variety and obscurity of the natural order could be reduced to the clarity and certainty of simple mathematical equations. Modern advances in understanding the mathematical laws of nature and the explosion of technological innovation rely on this supposition. But at what cost?  God’s glorious creation has fallen silent, emptied of spiritual reality, meaning, depth, mystery, purpose, moral law, and beauty, all of which have been transferred to the inner subjective world of the human mind. But how can we continue believing in the reality of meaning, depth, mystery, purpose, moral law, and beauty, if we think of them as existing only in the human psyche? They seem to be hanging in midair with no confirmation in common experience or foundation in an enduring reality.

Aristotle and all the ancients believed in the likeness and harmony between the human world and the natural world. This belief seemed reasonable, obvious even, because humans are part of the natural world. Galileo, Descartes and others split them apart, dividing the qualities we experience into the objective (real) and subjective (psychological) spheres. Human beings became islands of mind in a sea of mindless matter. It was inevitable that this division would become intolerable…that the human mind and soul would be reunited to nature by reducing them to something simpler. Sooner or later some thinker would do to the human soul what Galileo had done to the solar system.

And that “someone” was John Locke.

Who Are You My God? Is There A Way to Know?

How do you decide between Christianity and some other form of theism? In the first sixteen instilments of this study we’ve limited ourselves to reasoning from what is given always and everywhere to reason. We reasoned from the appearances of the natural world given through the senses and from the mind’s knowledge of itself gained by internal reflection to the ultimate explanation for the existence and operations of these things. Using these sources, we confronted three decision points where we had to make a choice between two explanations for our experience: (1) matter or mind, (2) an impersonal or a personal God, and (3) God as a part of nature or God as wholly transcending nature. The cumulative argument of the series so far amounts to this: believing in a personal God that wholly transcends nature can be based on a reasonable judgment and a responsible decision. I do not claim to have proved this conclusion beyond all doubt. I have not presented every argument for God’s existence or attempted to refute every argument against it. But I have presented what I believe to be the reasoning mind’s own drive toward God as the only explanation that does it justice. At this point, I must let the evidence speak for itself and move on.

The Fourth Decision Point

What is the first step one must take to transition from mere theism to Christian faith? As I admitted in previous posts, I don’t think there is only one path from unbelief to Christian faith. Different people make the transition differently. The order I wish to propose here makes sense to me because it addresses some concerns of our age and considers the questions our culture asks of Christians. If you can think of a better one, by all means follow it.

How does the Christian message enter the sphere of our reason so that we can assess its meaning and make a judgment about its truth? Clearly it is not given everywhere and always with nature. Nor is Christianity built into the structure of our minds. Hence Christianity is not merely a metaphysical explanation of the workings of nature or our minds. Nor can its coherence and truth can be judged only by its conformity with these perennially present structures. From where then does the information on which we can base a rational judgment and a responsible decision about Christianity come? Is there another source for truth relevant to the question of God and the appropriate human relationship to God? Or must our knowledge of God be derived solely from structures perennially available to us in nature or mind? (Deism insists on this limit.)

Two other options come to mind: (1) divine illumination or inspiration of every individual or (2) a unique event in history, a record of which is passed on in language to those not present at the event. I do not wish to deny the possibility or even the actual event of illumination or inspiration of individuals. After all, Saul of Tarsus (Paul the Apostle) claims to have experienced the resurrected Jesus Christ in a unique vision or revelation. And others since his time right up until today have made similar claims and experienced similar conversions. But I don’t think this is the norm. Today and for centuries past, most people meet the events on which Christianity is based in the form of language, that is, reports of the founding events that claim to derive from those who actually witnessed them.

Before we look at those reports, I want us to think about history as a source of information. By “history” I do not mean history in its proper sense. The “history” of historians is a reconstructed narrative of events based on a critical assessment of the sources that claim to have access to that event. For the historian, neither events themselves nor reports of events are “history” in the technical sense. But at this point I want to use the word history loosely to mean the entire fabric of past events. Natural scientists assume that past natural events and processes—though unique in their particular time and place and order— operated by the same physical laws as natural events and processes operate today. The eruption of Vesuvius in AD 79 was a unique natural event, but we assume that it can be explained by same physical laws that operate everywhere and at all times in the universe. In a sense, each natural event is new and unique; it cannot be repeated exactly. But these new and unique natural events do not reveal new natural laws. Only when natural events are brought into relationship with human and divine actions do they acquire the potential to reveal anything beyond natural law. (I will show how this works later.)

For the rest of this essay, I will use the term “history” to designate the complex flow of human actions and passions and interactions through time. In human history we see something we do not see in natural history, genuine novelty fueled by human freedom. I recognize that human beings’ free decisions are set in the context of certain stable features of human biology, psychology, and sociology and in relation to natural history. But I deny that human history can be explained wholly by such deterministic factors.  Writing, art, architecture, cities, poetry, and philosophy are in part products of human freedom and not merely determinations of the laws of nature. Because of the activity of human freedom, history is the realm of the new and unique. And the most significant of those new and unique things is the unique personhood of each individual human being. There never was and there never will be another Julius Caesar, Paul the Apostle, Abraham Lincoln, or you.

Why are other people are fascinating to us? Even though each person possesses a unique identity we cannot share, we can see in their stories realizations of possibilities, free actions, and sufferings which could be ours. Each person’s life history is a revelation of something humanity could be, of what you and I could be. Hence history may embody and the study of history may reveal something the study of nature and of the mind cannot get at: the possibilities of the human spirit both to create and become something that transcends the possibilities of the ordinary course of nature. Only in human history is such a revelation possible. It cannot be known abstractly because it is the product of freedom. It can be known only in its actual realization, and since the actual realization of personal identity happens in human individuals, we can come to know it only through personal revelation expressed in their acts, creations, and language. To know persons from the past we must rely on their stories recorded and passed down.

What if one individual realized the possibilities of human nature and freedom so completely and dramatically that this person’s life became the definitive revelation of human destiny and of divine identity? This is exactly what Christianity claims for Jesus Christ.

Next week we will begin our examination of the reports through which we get in contact with the story of Jesus Christ.
