"Nature is infallible and is the voice of God, with this difference, that the language of the Holy Scripture can and should be interpreted in many ways (otherwise it would say many things contrary to the evidence of the senses), but the language of Nature is always the same, without metaphor, without allegory, without hyperbole, without doubtful, obscure, mysterious meanings. Nature speaks clearly to him who knows how to understand her, and has no need of interpretation."
