Sciences are not to be rejected for the reason that they cause people to become insane when they seek wisdom from them in spiritual and heavenly matters, in which case they corrupt and blind. But if by means of them truths are supported, then they enlighten, because sciences are proper to mankind. Neither are pleasures of mind and body to be rejected for the reason that they destroy and blind people, but they are allowed to enjoy them for the use, as explained before [2506-8], provided they are joined to the uses. For pleasures are the life of the body, so they have also been given for uses. 1748, 4 July.
