This quote by Thomas Huxley is a warning against the risks of dogmatic thinking. Huxley is recommending that when science embraces a creed, it loses its capability to be open-minded and to question its own presumptions. This can cause a stagnation of development and a lack of innovation. By adhering to a single set of beliefs, science can become rigid and inflexible, unable to adjust to brand-new proof or concepts. Huxley's quote is a tip that science should remain available to new ideas and evidence, which it needs to never end up being too entrenched in any one set of beliefs. This is the only way for science to stay lively and alive.
