The knowledge of thyself will preserve thee from vanity.
A modern commentator made the observation that there re those who seek knowledge about everything and understand nothing. It is wonder - not mere curiosity - a sense of enchantment, of respect for the mysteries of love for the other, that is essential to the difference between a knowing that is simply a gathering of information and techniques and a knowing that seeks insight and understanding. It is wonder that reveals how intimate is the relationship between knowledge of the other and knowledge of the self, between inwardness and outwardness.
The freer a man’s judgment is in relation to a definite question, the greater is the necessity with which the content of this judgment will be determined; while the uncertainty, founded on ignorance, which seems to make an arbitrary choice among many different and conflicting possible decisions, shows precisely by this that it is not free, that it is controlled by the very object it should itself control. Freedom therefore consists in the control over ourselves and over external nature, an control founded on knowledge of natural necessity; it is therefore necessarily a product of historical development.
Freedom does not consist in the dream of independence from natural laws, but in the knowledge of these laws, and in the possibility this gives or systematically making them work towards definite ends. This holds good in relation both to the laws of external nature and to those which govern the bodily and mental existence of men themselves - two classes of laws which we can separate from each other at most only in thought but not in reality. Freedom of the will therefore means nothing but the capacity to make decisions with knowledge of the subject.
It is a welcome symptom in an age which is commonly denounced as materialistic, that it makes heroes of men whose goals lie wholly in the intellectual and moral sphere. This proves that knowledge and justice are ranked above wealth and power by a large section of the human race.
It is essential that the student acquire an understanding of and a lively feeling for values. He must acquire a vivid sense of the beautiful and of the morally good. Otherwise he - with his specialized knowledge - more closely resembles a well-trained dog than a harmoniously developed person.
To be a poet is to have a soul so quick to discern that no shade of quality escapes it, and so quick to feel that discernment is but a hand playing with finely ordered variety on the chords of emotion: a soul in which knowledge passes instantaneously into feeling, and feeling flashes back as a new organ of knowledge.
There lies before us, if we choose, continual progress in happiness, knowledge and wisdom. Shall we instead, choose death because we cannot forget quarrels? We appeal, as human beings, to human beings; remember your humanity and forget the rest. If you can do this, the way lies open to a new paradise; if you cannot, there lies before you the risk of universal death.
The usefulness of historical knowledge in philosophy, here as elsewhere, is that the prejudices of our own period may lose their grip on us if we imaginatively enter into another period, when people’s prejudices were different.
There is a sort of knowledge beyond the power of learning to bestow, and this is to be had in conversation; so necessary is this to the understanding the characters of men, that none are more ignorant of them than those learned pedants whose lives have been entirely consumed in colleges and among books; for however exquisitely human nature may have been described by writers the true practical system can be learned only in the world.
Education begins with life. Before we are aware the foundations of character are laid, and subsequent teaching avails but little to remove or alter them... If a man empties his purse into his head, no man can take it away from him. An investment in knowledge always pays the best interest.
