Two quotes illustrating a fundamental idea in St Augustine’s philosophical theology: the Image of God in human beings. The first from the Confessions shows his comparative epistemology, while the second is St Augustine’s starting point for his mediation on the Trinity. Blessed Feast day to you!
Is not this beauty visible to all whose senses are unimpaired? Why then does it not speak the same things unto all? Animals, the very small and the great, see it, but they are unable to question it, because their senses are not endowed with reason to enable them to judge on what they report. But men can question it, so that the invisible things of Him . . . are clearly seen, being understood by the things that are made; (Romans 1:20) but by loving them, they are brought into subjection to them; and subjects are not able to judge. Neither do the creatures reply to such as question them, unless they can judge; nor will they alter their voice (that is, their beauty), if so be one man only sees, another both sees and questions, so as to appear one way to this man, and another to that; but appearing the same way to both, it is mute to this, it speaks to that— yea, verily, it speaks unto all but they only understand it who compare that voice received from without with the truth within. For the truth declares unto me, Neither heaven, nor earth, nor any body is your God. This, their nature declares unto him that beholds them. They are a mass; a mass is less in part than in the whole. Now, O my soul, you are my better part, unto you I speak; for you animate the mass of your body, giving it life, which no body furnishes to a body but your God is even unto you the Life of life.
14. But since we treat of the nature of the mind, let us remove from our consideration all knowledge which is received from without, through the senses of the body; and attend more carefully to the position which we have laid down, that all minds know and are certain concerning themselves. For men certainly have doubted whether the power of living, of remembering, of understanding, of willing, of thinking, of knowing, of judging, be of air, or of fire, or of the brain, or of the blood, or of atoms, or besides the usual four elements of a fifth kind of body, I know not what; or,whether the combining or tempering together of this our flesh itself has power to accomplish these things. And one has attempted to establish this, and another to establish that. Yet who ever doubts that he himself lives, and remembers, and understands, and wills, and thinks, and knows, and judges? Seeing that even if he doubts, he lives; if he doubts, he remembers why he doubts; if he doubts, he understands that he doubts; if he doubts, he wishes to be certain; if he doubts, he thinks; if he doubts, he knows that he does not know; if he doubts, he judges that he ought not to assent rashly. Whosoever therefore doubts about anything else, ought not to doubt of all these things; which if they were not, he would not be able to doubt of anything.
