No man of high and generous spirit is ever willing to indulge in flattery; the good may feel affection for others, but will not flatter them.
AristotleWhether we call it sacrifice, or poetry, or adventure, it is always the same voice that calls.
AristotleThose who assert that the mathematical sciences say nothing of the beautiful or the good are in error. For these sciences say and prove a great deal about them; if they do not expressly mention them, but prove attributes which are their results or definitions, it is not true that they tell us nothing about them. The chief forms of beauty are order and symmetry and definiteness, which the mathematical sciences demonstrate in a special degree.
