Science does not limit itself merely to what is currently verifiable. But it is interested in questions that are potentially verifiable (or, rather, falsifiable).
Sentiment: POSITIVE
There must be no barriers to freedom of inquiry. There is no place for dogma in science. The scientist is free, and must be free to ask any question, to doubt any assertion, to seek for any evidence, to correct any errors.
Science goes from question to question; big questions, and little, tentative answers. The questions as they age grow ever broader, the answers are seen to be more limited.
Science is about exploring the unknown and cannot offer guarantees.
Science is not, despite how it is often portrayed, about absolute truths. It is about developing an understanding of the world, making predictions, and then testing these predictions.
There cannot be any impediment to science that will ultimately be good to the general public.
There is an ever-widening gap between what science allows and what we should actually do. There are many doors science can open that should be kept closed, on prudential or ethical grounds.
I don't think you can impose limits on science because the very nature of homo sapiens is that he - she - is an inquisitive species. You can't control science. You have to control the effects of science.
Science has everything to say about what is possible. Science has nothing to say about what is permissible.
Science is based solely on doubt-based, disinterested examination of the natural and physical world. It is entirely independent of personal belief. There is a very important, fundamental concomitant - that is to accept absolutely nothing whatsoever, for which there is no evidence, as having any fundamental validity.
Science is defined in various ways, but today it is generally restricted to something which is experimental, which is repeatable, which can be predicted, and which is falsifiable.
