“Bad books are intellectual poison; they destroy the mind.”
Books are the best of things, well used; abused, among the worst. What is the right use? What is the one end, which all means go to effect? They are for nothing but to inspire.
Some books are to be tasted, others to be swallowed, and some few to be chewed and digested: that is, some books are to be read only in parts; others to be read, but not curiously; and some few to be read wholly, and with diligence and attention.
Buying books would be a good thing if one could also buy the time to read them in: but as a rule the purchase of books is mistaken for the appropriation of their contents.
Lock up your libraries if you like; but there is no gate, no lock, no bolt that you can set upon the freedom of my mind.
So it comes about that if anyone spends almost the whole day in reading, and by way of relaxation devotes the intervals to some thoughtless pastime, he gradually loses the capacity for thinking; just as the man who always rides, at last forgets how to walk.
You must linger among a limited number of master-thinkers, and digest their works, if you would derive ideas which shall win firm hold in your mind.
Books are the mirrors of the soul.
In reading of many books is distraction. Accordingly, since you cannot read all the books which you may possess, it is enough to possess only as many books as you can read.
Those who are slaves to their appetites cannot preserve their reason, their memory, or their senses in their full vigour; for a full belly does not produce a fine mind.
Read not the Times. Read the Eternities. Conventionalities are at length as bad as impurities.
Learning will be cast into the mire and trodden down under the hoofs of a swinish multitude.
If you wish to have leisure for your mind, either be a poor man, or resemble a poor man. Study cannot be helpful unless you take pains to live simply; and living simply is voluntary poverty.
For what are the classics but the noblest recorded thoughts of man?
He whose intellect overcomes his desire is higher than the angels; he whose desire overcomes his intellect is less than an animal.
You are no doubt aware that the Almighty, desiring to lead us to perfection and to improve our state of society, has revealed to us laws which are to regulate our actions. These laws, however, presuppose an advanced state of intellectual culture. We must first form a conception of the Existence of the Creator according to our capabilities; that is, we must have a knowledge of Metaphysics. But this discipline can only be approached after the study of Physics: for the science of Physics borders on Metaphysics, and must even precede it in the course of our studies, as is clear to all who are familiar with these questions.
There is no area in our minds reserved for superstition, such as the Greeks had in their mythology; and superstition, under cover of an abstract vocabulary, has revenged itself by invading the entire realm of thought. Our science is like a store filled with the most subtle intellectual devices for solving the most complex problems, and yet we are almost incapable of applying the elementary principles of rational thought. In every sphere, we seem to have lost the very elements of intelligence: the ideas of limit, measure, degree, proportion, relation, comparison, contingency, interdependence, interrelation of means and ends. To keep to the social level, our political universe is peopled exclusively by myths and monsters; all it contains is absolutes and abstract entities. This is illustrated by all the words of our political and social vocabulary: nation, security, capitalism, communism, fascism, order, authority, property, democracy. We never use them in phrases such as: There is democracy to the extent that... or: There is capitalism in so far as... The use of expressions like "to the extent that" is beyond our intellectual capacity. Each of these words seems to represent for us an absolute reality, unaffected by conditions, or an absolute objective, independent of methods of action, or an absolute evil; and at the same time we make all these words mean, successively or simultaneously, anything whatsoever. Our lives are lived, in actual fact, among changing, varying realities, subject to the casual play of external necessities, and modifying themselves according to specific conditions within specific limits; and yet we act and strive and sacrifice ourselves and others by reference to fixed and isolated abstractions which cannot possibly be related either to one another or to any concrete facts. In this so-called age of technicians, the only battles we know how to fight are battles against windmills.
Thinking is the hardest work there is, which is the probable reason why so few engage in it.
No man is entirely free from weakness and imperfection in this life. Men of the most exalted genius and active minds are generally most perfect slaves to the love of fame. They sometimes descend to as mean tricks and artifices in pursuit of honor or reputation as the miser descends to in pursuit of gold.
There are some men who expose themselves to damnation so foolishly by avarice, by brutality, by debauches, by violence, by excesses, by blasphemies! ...it is always a great folly for a man to expose himself to damnation... He must despise desire and its kingdom, and aspire to that kingdom of love in which all the subjects breathe nothing but love, and desire nothing but the benefits of love.
Strong minds discuss ideas, average minds discuss events, weak minds discuss people.
Iron rusts from disuse; stagnant water loses its purity and in cold weather becomes frozen; even so does inaction sap the vigor of the mind.
When we read, another person thinks for us: we merely repeat his mental process.
Hatred and anger are the greatest poison to the happiness of a good mind.
Reserve your right to think, for even to think wrongly is better than not to think at all.
It is natural for a man's character and actions to be influenced by his friends and associates and for him to follow the local norms of behavior. Therefore, he should associate with the righteous and be constantly in the company of the wise, so as to learn from their deeds. Conversely, he should keep away from the wicked who walk in darkness, so as not to learn from their deeds.
