Kein Zweig der menschlichen Kenntnisse bietet anziehendere Ergebnisse dar und erlaubt wichtigere Anwendungen auf das thätige Leben, als die Astronomie; aber keine — wir müssen es mit Beschämung gestehn — wenigstens bei uns Deutschen, ist weniger verbreitet als sie. Es ist wahrhaft empörend, wenn man, trotz der großen Anzahl von Lehrbüchern, in jedem Jahre Männer, die sich zu den Gebildeten, ja Gelehrten, zählen, auftreten sieht, um in Druckschriften die gröbste Unwissenheit zur Schau zu legen. Fast scheint es, daß die allgemein gefürchtete Mathematik auch die Astronomie in ihren Bann mit fortgerissen habe. Auch läßt sich nicht leugnen, daß es für einen der mathematischen Sprache unkundigen Leser ein sehr unangenehmes Geschäft ist, die Schlüsse mühsam aus den ihm unverständlichen Beweisen herauszusuchen, und die Mathematik selbst verlangt in der That ein viel zu ernstes Studium, und erscheint dem Anfänger zu schwer und zu trocken, als daß man sie in den schon so weiten Studienkreis der Gebildeten ziehen könnte, und die ersten Anfangsgründe reichen zum Verstehn der Astronomie bei weitem nicht aus. Zwar kündigen sich mehrere astronomische Lehrbücher als populär an, allein wenn die Leser, durch den Titel getäuscht, eine durchgängig verständliche Darstellung der Astronomie erwarten, so finden sie entweder die Mathematik in andrer Gestalt, wie bei Schuberts populärer Astronomie und La Place’s Exposition du système du monde, oder einen solchen Mangel an Gründlichkeit und Vollständigkeit, daß sie ihren Zweck nicht erreichen.
