The philosopher ... subjects experience to his critical judgment, and this contains a value judgment namely, that freedom from toil is preferable to toil, and an intelligent life is preferable to a stupid life. It so happened that philosophy was born with these values. Scientific thought had to break this union of value judgment and analysis, for it became increasingly clear that the philosophic values did not guide the organisation of society.
Herbert Marcuse
A great part of its theories derives an additional charm from the peculiarity that important propositions, with the impress of simplicity on them, are often easily discovered by induction, and yet are of so profound a character that we cannot find the demonstrations till after many vain attempts; and even then, when we do succeed, it is often by some tedious and artificial process, while the simple methods may long remain concealed.
Carl Friedrich Gauss
To sum up: numbers appear to represent both an attribute of matter and the unconscious foundation of our mental process. For this reason, number forms, according to Jung, that particular element that unites the realms of matter and psyche. It is "real” in a double sense, as an archetypal image and as a qualitative manifestation in the realm of outer-world experience.
Marie-Louise von Franz
In doing good, we are generally cold, and languid, and sluggish and of all things afraid of being too much in the right. But the works of malice and injustice are quite in another style. They are finished with a bold, masterly hand touched as they are with the spirit of those vehement passions that call forth all our energies, whenever we oppress and persecute.
Edmund Burke
Geometry is of much assistance in architecture, and in particular it teaches us the use of the rule and compasses, by which especially we acquire readiness in making plans for buildings in their grounds, and rightly apply the square, the level, and the plummet. By means of optics the light in buildings can be drawn from fixed quarters of the sky. Difficult questions involving symmetry are solved by means of geometrical theories and methods.
Vitruvius
