The secrets of nature are concealed; her agency is perpetual, but we do not always discover its effects; time reveals them from age to age; and although she is always the same in herself, she is not always equally well known.
Blaise PascalSince we cannot be universal and know all that is to be known of everything, we ought to know a little about everything. For it is far better to know something about everything than to know all about one thing. This universality is the best. If we can have both, still better; but if we must choose, we ought to choose the former.
Blaise Pascal
