A Case of Conscience

James Blish


Father Ruiz-Sanchez was a dedicated man — a priest who was also a scientist, and a scientist who was also a human being. He found no insoluble conflicts in his beliefs or in his ethics until he was sent to Lithia.
      There he came upon a race of aliens — reptilian in form — who were admirable in every way except for their total reliance on cold reason; they were incapable of faith and belief. On Lithia, Father Ruiz-Sanchez also found a scientific riddle, and he was presented with an ethical problem that reached across two worlds.
      Father Ruiz-Sanchez was then torn in a struggle between the teachings of his faith, the teachings of his science, and the inner promptings of his humanity. There was only one solution. He had to accept an ancient and unforgivable heresy — and, in accepting that heresy, he risked the futures of both worlds.
      This is the first book of the quartet of books called After Such Knowledge. Book two of the series, Doctor Mirabilis, will be available later in 2021 and books three and four, Black Easter and The Day After Judgment, will be available in 2022.
      This new edition of A Case of Conscience has an introduction by Greg Bear, new cover artwork by Pascal Casolari, new interior art by Allen Koszowski, and archival artwork by Darrell K. Sweet. The signed edition is limited to 300 signed and numbered copies. Each book is signed by Greg Bear and Allen Koszowski, with an Estate-approved facsimile signature by James Blish.
       The specifications for this set are: one book, printed in four colors and one color throughout, bound in European cloth with two hits of foil stamping, top-edge stain, ribbon marker, patterned endpapers, and a handsome dustjacket. Note: when you buy the book, either the signed edition (now sold out) or the Gift Edition, we keep track of your order and you will have first chance to buy the remaining three books in the series, so you will not miss out! Thank you!
