"Many places in the Vedic literature attest to what may be called a pre-scientific interest in and study of the world, and to attempts at systematizing the knowledge resulting from this study. Much attention is paid to chronology and the calendar... astronomy, cosmology, and cosmogony. This scientific concern is wholly determined by man's ritual and religious interests and constitutes an integral part of one and the same harmonious view of life and the world. This does not, however, exclude the occurrence of references to a certain knowledge of anatomy, embryology, and medical practice. Nor did some linguistic facts—as far as they were utilizable for ritual purposes—escape the authors' notice."
