Be wary of extremes: the green and the over-ripe fruit causes the worst pain.

Sorrow causes more absence of mind and confusion than so-called levity.

The ignorant man is not onlyh agitated by external causes in many ways, and never enjoys true peace of soul, but lives also ignorant, as it were, both of God an of things, and as soon as he ceases to suffer ceases also to be. On the other hand, the wise man, in so far as he is considered as such, is scarcely ever moved in his mind, but, being concscious by a certain eternal necessity of himself, of God, and of things, never ceases to be, and always enjoys true peace of soul.

The four great motives which move men to social activity are hunger, love, vanity, and fear of superior powers. If we search out the causes which have moved men to war we find them under each of these motives or interests.

Ignorance and inconsideration are the two great causes of the ruin of mankind.

Man's mind cannot grasp the causes of events in their completeness, but the desire to find the causes is implanted in man's soul.

Adversity causes some men to break; others to break records.

Let's learn and label properly Disappointment and Discouragement for what they are - two completely different states of mind. Disappointment can be a spur to improvement that will contribute to success. But Discouragement is a mortal enemy that destroys courage and robs one of the will to fight. It is not circumstance that causes Discouragement, but one's own reaction to that circumstance. Everyone must meet Disappointment, many times; it is simply a part of life. When it is met, we may resign ourselves to Discouragement and failure. Or we may recognize each Disappointment as an asset by which we can profit, and take new strength from a lesson learned. The choice is ours, each time, to make.

One of the prime causes of unhappiness in the world is approval-seeking.

If there is free will, all things do not happen according to fate; if all things do not happen according to fate, there is not a certain order of causes; and if there is not a certain order of causes, neither is there a certain order of things foreknown by God - for things cannot come to pass except they are preceded by efficient causes - but if there is no fixed and certain order of causes foreknown by God, all things cannot be said to happen according as He foreknew that they would happen... But it does not follow that, though there is for God a certain order of all causes, there must therefore be nothing depending on the free exercise of our own wills, for our wills themselves are included in that order of causes which is certain to God and is embraced by His foreknowledge, for human wills are also causes of human actions; and He Who foreknew all the causes of things would certainly among those causes not have been ignorant of our wills.

He who eats much evacuates much, and he who increaseth this flesh multiplieth food for worms; but he who multiplieth good works causes peace within himself.

The man who causes the deed is greater than he who does it.

Mistakes are costly and somebody must pay. The time to correct a mistake is before a mistake is made. The causes of mistakes are first, "I didn't know"; second, "I didn't think"; third, "I didn't care."

Everything is a succession of appearances whose source is the accumulation of causes and conditions.

Peace is not the elimination of the causes of war. Rather it is a mastery of great human forces and the creation of an environment in which human aims may be pursued constructively.

The dreary thing about most new causes is that they are praised in such very old terms. Every new religion bores us with the same stale rhetoric about closer fellowship and the higher life.

Love naturally reverses the idea of obedience, and causes the struggle between any; two who truly love each other to be, not who shall command, but who shall yield.

(Mathematical Division of Things, is never made in Minima; but Things may be Physically divided into their least parts; as when Concrete Matter is so far divided that it departs into Physical Monades, as it was in the first State of its Materiality...) Moreover the consideration of this Infinite Divisibility of every thing, into parts always less, is no unnecessary or unprofitable Theory, but a thing of great moment; viz. that thereby may be understood the Reasons and Causes of Things; and how all Creatures from the highest to the lowest are inseparably united with one another, by means of Subtiler Parts interceding or coming in between, which are the Emanations of one Creature into another, by which also they act one upon another at the greatest distance; and this is the Foundation of all Sympathy and Antipathy which happens in Creatures: And if these things be well understood of any one, he may easily see into the most secret and hidden Causes of Things, which ignorant Men call occult Qualities.

Ambition is a spirit in the world that causes all the ebbs and flows of nations, keeps mankind sweet by action; without that, the world would be a filthy, settled mud.

He is unworthy of life, that causes not life in another.
