“Compassion for animals is intimately connected with goodness of character, and it may be confidently asserted that he, who is cruel to living creatures, cannot be a good man. Moreover, this compassion manifestly flows from the same source whence arise the virtues of justice and loving-kindness towards men.”

Novum Organum (1620), Book I
Context: The beginning is from God: for the business which is in hand, having the character of good so strongly impressed upon it, appears manifestly to proceed from God, who is the author of good, and the Father of Lights. Now in divine operations even the smallest beginnings lead of a certainty to their end. And as it was said of spiritual things, “The kingdom of God cometh not with observation,” so is it in all the greater works of Divine Providence; everything glides on smoothly and noiselessly, and the work is fairly going on “before men are aware that it has begun. Nor should the prophecy of Daniel be forgotten, touching the last ages of the world: —“Many shall go to and fro, and knowledge shall be increased;” clearly intimating that the thorough passage of the world (which now by so many distant voyages seems to be accomplished, or in course of accomplishment), and the advancement of the sciences, are destined by fate, that is, by Divine Providence, to meet in the same age.
