All the great amusements are dangerous for the Christian life.
Madeleine de Souvre, marquise de SableNothing can tell us so much about the general lawlessness of humanity as a perfect acquaintance with our own immoderate behavior. If we would think over our own impulses, we would recognize in our own souls the guiding principle of all vices which we reproach in other people; and if it is not in our very actions, it will be present at least in our impulses. There is no malice that self-love will not offer to our spirits so that we may exploit any occasion, and there are few people virtuous enough not to be tempted.
Madeleine de Souvre, marquise de SableWe often value the exterior and superficial aspect of things more than their inner reality. Bad manners taint everything even justice and reason. The 'how' of things matters most, and even the most disagreeable matters can be sweetened and gilded over with the proper appearance. Such is the bias and the weakness of the human mind.
Madeleine de Souvre, marquise de SableWhen an opinionated person starts to challenge something, his mind shuts out all that could clear up the matter. The argument irritates him, however just it might be, and it seems that he is afraid of discovering the truth.
