I've written several blogs on the contrasts between science and philosophy. Having been educated in science and having pursued a career in it, I find it to be more understandable than philosophy. My logical scientific mind has often struggled to comprehend the imprecise nature of philosophical reasoning and debate.
Long after retirement, I have drifted away from science's demands for exactness and increasingly into philosophy's realm of fuzziness. I have come to appreciate philosophy and its search for knowledge. I have come to understand that science and philosophy really have very similar goals—as seen by their similar etymological roots. The word science stems from the Latin word scientia, which means “to know.” The word philosophy stems from the Greek word philosophia, which means “love of wisdom.” So they both are about knowledge, learning, logic, understanding, and truth.
I believe that there are, however, several distinct differences between science and philosophy—differences that sometimes can be very significant, especially in the manner in which adherents of each discipline pursue knowledge; in fact, differences that even can create antagonisms between them. A few of these disparities have spoken to me in recent years, as I've come to be more comfortable with the philosophical approach to gaining insight and wisdom. Here are five differences—not a complete list by any means, but the salient ones that I've encountered.
First, while science is precise, philosophy tends to be indistinct and often inexact. While science is quantitative, philosophy is qualitative. Scientists want repeatability and they use procedures that many others can follow, importantly to obtain the same results. A scientific theory does not become widely accepted until many different scientists follow comparable paths and come to the same conclusions. Philosophers, however, often take very different paths, come to different conclusions, and vehemently disagree with each other. They love to engage in seemingly endless disputes.
Second, science deals with “what is,” while philosophy often considers “what ought to be.” Morality often is a central part of philosophy, while science is amoral—though not at all immoral. Science studies Nature, which just is. So being right or wrong in a moral sense is irrelevant.
Third, science is structured such that, step by step, researchers relentlessly close in on a definitive answer. It often is a cooperative effort, as scientific teams work in concert to merge to a solution. Although philosophers also seek solutions, they often work individually and think in very different ways from each other, so they will sometimes come to a conclusion that is viewed as essentially false by fellow philosophers. Hence, the source of endless debates.
Fourth, while science addresses the whole cosmos—thus we have countless scientific disciplines—philosophy is focused on the human mind. To science the human mind is but the tiniest sliver of its domain. This is a primary reason why philosophy tends to be so subjective: it's the human mind studying the human mind. It's bound to be a bit parochial, opinionated, and even prejudiced.
Fifth, while science relentlessly progresses over time—gradually seeking answers and building its knowledge base—philosophy seems to be wrestling with the same questions today that it faced two to three millennia ago. Has philosophy not progressed as much? Do the questions posed by philosophers have no definitive answers? Are the questions so complex and vague that conclusive answers may never come? Are philosophers asking unanswerable questions?
There's a little truth in all these questions, but I suspect there's another possibility why philosophers continue to ponder many of the same questions, century after century. I think that a major factor of philosophy's apparent sluggishness is due to that unique quality it has: its attention to morality. Philosophers—like prophets—often offer messages to the masses that the people do not want to hear. Uncomfortable truths—like scientists’ global-warming message—can be clearly laid out, but people (especially political leaders) often refuse to listen. Thus, while humanity could progress and change for the better, the cost is often regarded as too high to pay. We'd rather bask in our existing laziness, than put hard work into positive and necessary change.
A philosopher once said that philosophy is “the right way to think about things.” In that statement right there we can see a big contrast between science and philosophy: science doesn't give a hoot if our thinking is the right way or not—its truths are independent of the human mind's rightness of thinking.
