The following is from the Preface to the first edition of Rudolf Steiner's seminal work The Philosophy of Freedom, first published in 1894 and revised in 1918:
[W]e do not want any knowledge of the kind that has become frozen once and for all into rigid academic rules, preserved in encyclopedias valid for all time. Each of us claims the right to start from the facts that lie nearest to hand, from his own immediate experiences, and thence to ascend to a knowledge of the whole universe. We strive after certainty in knowledge, but each in his own way.
Yes. And this is precisely the mind-set that is capable of producing the artist and/or the saint.
