Trust Science but Not Logic? Think Again

The evidence of Hashem’s presence can be seen across every scientific field, from the smallest cell examined in biology to the largest galaxies explored by astronomy. Throughout the universe, there is an extraordinary order and precision, far beyond anything humans can produce, pointing to a guiding intelligence.

Yet despite these striking realities, some people dismiss any conclusions drawn from them by saying, “I trust science, not logic.” The mistake here is failing to recognize that science itself is built entirely on logic.

Why Science Cannot Exist Without Logic

Let’s illustrate this with a simple example. Professor Eliav sits in his laboratory, studying the behavior of bacteria under a microscope. He observes their movements and how they react to various substances. At some point, he turns away from the microscope to record his findings in his journal.

At that moment, he is no longer looking at the bacteria. How does he know they are still there? How does he know they did not suddenly disappear the instant he looked away? How does he know they continue to behave in the same way?

The answer is logic. Based on past experience and consistent observation, the professor logically concludes that the bacteria did not vanish simply because he stopped watching them.

Trusting Knowledge and Memory

The same question can be asked on a deeper level. How does the professor know that everything he has learned until now reflects reality and was not simply a deception by countless people before him? How does he know his own memory is reliable?

Here too, logic is at work. He draws conclusions about human nature, the consistency of memory, and the stability of reality itself. These assumptions are not scientific measurements. They are logical foundations that make science possible.

As we can see, the professor does not rely only on his senses. His observations are accompanied by intellectual interpretation. That interpretation is logic.

Cause, Effect, and the Structure of Reality

All scientific research rests on the logical principle that there is a connection between cause and effect, between events that precede and outcomes that follow. From this same logic comes trust in statistics, patterns, and predictions about both the past and the future.

Without logic, science cannot function. Without logic, no knowledge about reality can be established at all.

Think of the senses and scientific instruments as tools that present raw data. Logic is the inner system that evaluates that data, deciding what to accept, what to reject, and how to interpret it. Logic is the final authority that gives meaning to information.

Logic and the Recognition of the Creator

Through logic, we gain scientific knowledge about the world. And through that same logic, we can arrive at grounded and meaningful recognition of the Creator.

Professor David Weiss, a physician and cancer researcher, once explained this clearly in an interview. “As a scientist,” he said, “I am constantly seeking order in the world, whether in immunology or cell biology. To explain not only the creation of the universe, but even the fact that this atom or molecule exists in a stable, organized form instead of exploding, I must assume the existence of a great architect.”

Science does not replace logic. It depends on it. And logic, when followed honestly, leads far beyond the laboratory, toward recognition of the One who designed the order science seeks to understand.
