Reason is God's gift; but so are the passions. - John Henry Newman

[W]hether we will believe it or no, the truth remains, that the strength of the Church, as heretofore, does not lie in earthly law, or human countenance, or civil station, but in her proper gifts; in those great gifts which our Lord pronounced to be beatitudes. Blessed are the poor in spirit, the mourners, the meek, the thirsters after righteousness, the merciful, the pure in heart, the peace makers, the persecuted.

Moreover, there is this harm too, and one of vast extent, and touching men generally, that by insincerity and lying faith and truth are lost, which are the firmest bonds of human society, and, when they are lost, supreme confusion follows in life, so that men seem in nothing to differ from devils.

The natural truths of science, physical, moral, social, political, material, are all from God—as those of the supernatural order are. Man abused supernatural truths in the medieval time, as well as used them; and now man uses natural truths, as well as abuses them. I am not determining which of the two abuses is the greater profanation, I only say that the one age is not all light, the other all darkness; and I think that, in matter of fact, more can be said for this age than you seem to allow.
