The laws of nature are the rules according to which the effects are produced; but there must be a cause which operates according to these rules. The rules of navigation never navigated a ship; the rules of architecture never built a house.

If one should tell of a telescope so exactly made as to have the power of seeing; of a whispering gallery that had the power of haring; of a cabinet so nicely framed as to have the power of memory; or of a machine so delicate as to feel pain when it was touched - such absurdities are so shocking to common sense that they would not find belief even among savages; yet it is the same absurdity to think that the impressions of external objects upon the machine of our bodies can be the real efficient cause of thought and perception.

Smallness of mind is the cause of stubbornness, and we do not credit readily what is beyond our view.

No more by the law of reason than by the law of nature can anything occur without a cause.

It is a very easy thing to devise good laws; the difficulty is to make them effective. The great mistake is that of looking upon men as virtuous, or thinking that they can be made so by laws; and consequently the greatest art of a politician is to render vices serviceable to the cause of virtue.

Even in a righteous cause force is a fearful thing; God only helps when men can help no more.

Evolutionism, purporting to explain all and everything solely and exclusively by natural selection for adaption and survival, is the most extreme product of the materialistic utilitarianism of the nineteenth-century. The inability of twentieth-century thought to rid itself of this imposture is a failure which may well cause the collapse of the Western civilization.

The great secret of success is to go through life as a man who never gets used up. That is possible for him who never argues and strives with men and facts, but in all experiences retires upon himself, and looks for the ultimate cause of things in himself.

Often the cause of death is the fear of dying.

Teachers should be held in the highest honor. They are the allies of legislators; they have agency in the prevention of crime; they aid in regulating the atmosphere, whose incessant action and pressure cause the life-blood to circulate, and to return pure and healthful to the heart of the nation.

A species does not live within its environment; it interacts with it. Over a period of time a species can interact so violently that the changes it catalyzes can cause it to change dramatically--even to die out. Scientists estimate that 90% of the life forms that have inhabited our planet are now extinct. From the earliest single-cell life form to the human animal, all have interacted with the environment. All have created problems for themselves. All have been agents of evolutionary change. All have experienced evolution through cataclysm.

Thoughts are behavior. The mind is like a muscle which can be improved with practice. Many 'habits' are a result of poor thinking skills. We play thoughts over and over which keep us distracted from effective problem solving. When out-of-control thoughts run around inside our heads they cause anxiety. We then focus on unproductive thoughts and ideas.

Love is nothing but joy accompanied with the idea of an eternal cause, and hatred is nothing but sorrow with the accompanying idea of an external cause...

Love is nothing else but pleasure accompanied by the idea of an external cause: hate is nothing else but pain accompanied by the idea of an external cause.

Neither in God nor outside God is there any cause or reason which can negate His existence, and therefore God necessarily exists.

Prior events are causes of those following them, and in this manner all things are bound together with one another, and thus nothing happens in the world such that something else is not entirely a consequence of it and attached to it as a cause... From everything that happens something else follows depending on it by necessity as cause.

The end is the source of everything that exists in the cause and the end of everything that exists in the effect... end, cause and effect, exist in the greatest and least things... To think from ends is the method of wisdom, from causes that of intelligence, and from effects that of knowledge. From this it may be seen that all perfection increases in and according to the ascent to higher degrees.

What can be more foolish than to think that all this rare fabric of heaven and earth could come by chance, when all the skill of art is not able to make an oyster? To see rare effects, and no cause; a motion, without a mover; a circle, without a centre; a time, without an eternity; a second, without a first: these are things so against philosophy and natural reason, that he must be a beast in understanding who can believe in them. The thing formed, says that nothing formed it; and that which is made, is, while that which made it is not! This folly is infinite!

Mere success is one of the worst arguments in the world of a good cause, and the most improper to satisfy conscience: and yet in the issue it is the most successful of all other arguments, and does in a very odd, but effectual, way, satisfy the consciences of a great many men, by showing them their interest.

Taken as a whole, men will only devote their enthusiasm, their time, and their energy to matters in which their passions have a personal interest. But their personal interests, however powerful they may be, will never carry them very far or very high unless they can be made to seem noble and legitimate in their own eyes by being allied to some good cause in which the whole human race can join.
