Knowledge is proud that he has learned so much; wisdom is humble that he knows no more.

To make a man happy, fill his hands with work, his heart with affection, his mind with purpose, his memory with useful knowledge, his future with hope, and his stomach with food. The devil never enters a man except one of these rooms be vacant.

Even a monotonously undeviating path of self-examination does not necessarily lead to a mountain of self-knowledge.

Genuine intellectual integrity is found in experimental knowing. Until this lesson is fully learned, it is not safe to dissociate knowledge from experiment nor experiment from experience.

Neither wealth nor knowledge can provide effective ways to deal with human excesses.

Knowledge has outstripped character development, and the young today are given an education rather than an upbringing.

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.

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.

Whoever undertakes to set himself up as a judge in the field of truth and knowledge is shipwrecked by the laughter of the gods.

It is in those acts called trivialities that the seeds of joy are forever wasted, until men and women look around with haggard faces at the devastation their own waste has made, and say the earth bears no harvest of sweetness, calling their denial knowledge.

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.

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.

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.

The surest method of arriving at a knowledge of God's eternal purposes about us is to be found in the right use of the present moment. Each hour comes with some little faggot of God's will fastened upon its back.

The best reward of a kindly deed is the knowledge of having done it.

Knowledge is the treasure of the mind, but discretion is the key to it, without which it is useless. The practical part of wisdom is the best.

Perfection is immutable. But for things imperfect, change is the way to perfect them. It gets the name of willfulness when it will not admit of a lawful change to the better. Therefore constancy without knowledge cannot be always good. In things ill it is not virtue, but an absolute vice.

Knowledge will not be acquired without pains and application. It is troublesome and deep digging for pure waters; but when once you come to the spring, they rise up and meet you.

Our task is to discover the primordial, absolutely unconditioned first principle of all human knowledge... It is intended to express that Act which does not and cannot appear among the empirical states of our consciousness, but rather is at the basis of all consciousness and alone makes it possible.
