The limits of science is a controversial topic and one that I am passionate about. Here I'll share 15 perspectives on the limits of science.

  1. Professor Nicholas Rescher wrote in The Limits of Science that the knowledge science gives us is descriptive rather than normative and that science is devoid of the element of personalized evaluation, and is value neutral.1

  2. Philosophy of science professor Samir Okasha from the University of Bristol wrote in Philosophy of Science: A Very Short Introduction that questions in philosophy like the nature of knowledge, mortality, or happiness appear non-soluble by scientific means. There is no branch of science that tells us what knowledge is or what happiness means to humans. According to Samir, these are philosophical questions.2

  3. Understanding Science founded by scientists and teachers at UC California and Berkley wrote that science doesn’t make moral judgements, aesthetic judgements, and doesn’t tell us how to use scientific knowledge.3

  4. Author Bryan Appleyard in Understanding the Present: Science and the Soul of Modern Man wrote that science has always worked diligently to avoid being a religion, faith, or morality, and that it does not make moral judgements.4

  5. William Harris from How Stuff Works wrote that the limitations of science are based on the fact that a hypothesis must be testable and that experiments be repeatable, which places certain topics beyond the reach of the scientific method. According to Harris, science also doesn’t make moral judgements.5

  6. Author and researcher in cognitive science Jamie Hale in explaining the scientific method wrote that science doesn’t make claims of absolutism and doesn’t claim to have all the answers. The tentative nature of scientific knowledge is one of its strong points.6

  7. Professor Susan Haack in Defending Science wrote that science is a human enterprise with natural foibles, and that it focuses on basic things like extending reasoning power, expanding our imagination, and valuing evidence.7

  8. Biologist and author Rupert Sheldrake in Science Set Free wrote that science is a human activity and that it is important to recognize it as such so that it doesn’t distort the public’s perception of scientists and the perception scientists have of themselves.8

  9. Professor Jan Faye in Rethinking Science wrote that the sciences are limited to the point at which hypotheses are empirically underdetermined. He wrote in his conclusion that it is in metaphysics that we seek an ultimate comprehensive interpretation of life.9

  10. Examining the limits of science from various philosophers of science, science correspondent and radio host Robert Krulwich agreed that there will be questions science will never be able to answer.10

  11. Award winning astrophysicist and popular scientist Martin Rees wrote that it would be naïve to think that science can answer everything.11

  12. Twentieth century philosopher of science Karl Popper said in in a lecture he gave at Darwin College that it’s important to realize science doesn’t make assertions about ultimate questions.12

  13. Philosophy of science professor Stephen Carey in A Beginners Guide to Scientific Method wrote that scientific explanation is focused on the natural world and focuses on things like causes, laws, and mechanisms. He wrote the deep metaphysical questions that have vexed philosophers for millennia will likely not be settled by scientific inquiry. Examples of such questions are why is there something rather than nothing at all? What is the meaning of life? Stephen wrote that this is not a downside of science; it’s merely outside of the purview of scientific inquiry. He went on to write that even if science did create a complete theory of the world, there will still be untouched metaphysical questions.13

  14. Physicist Marcelo Gleiser in The Island of Knowledge wrote that science alone won’t answer all questions, and said it is a misguided hope to think that science will. He wrote that to accept the provisional nature of our knowledge is not a defeat, but places science within the fallible, human realm.14

  15. Scientist and noble laureate Peter Medawar in The Limits of Science wrote that for questions of first and last things we must turn to metaphysics.15
