To me there has never been a higher source of earthly honor or distinction than that connected with advances in science.

A man may imagine things that are false, but he can only understand things that are true, for if the things be false, the apprehension of them is not understanding.

I can calculate the motion of heavenly bodies, but not the madness of people.

We build too many walls and not enough bridges.

To myself I am only a child playing on the beach, while vast oceans of truth lie undiscovered before me.

It is the weight, not numbers of experiments that is to be regarded.

We are to admit no more causes of natural things than such as are both true and sufficient to explain their appearances.

To me there has never been a higher source of earthly honor or distinction than that connected with advances in science.

I was like a boy playing on the sea-shore, and diverting myself now and then finding a smoother pebble or a prettier shell than ordinary, whilst the great ocean of truth lay all undiscovered before me.

If I have seen further than others, it is by standing upon the shoulders of giants.

Tact is the art of making a point without making an enemy.

To every action there is always opposed an equal reaction.

Errors are not in the art but in the artificers.

If I have done the public any service, it is due to my patient thought.

Absolute space, in its own nature, without regard to anything external, remains always similar and immovable. Relative space is some movable dimension or measure of the absolute spaces, which our senses determine by its position to bodies, and which is vulgarly taken for immovable space.

All variety of created objects which represent order and life in the universe could happen only by the willful reasoning of its original Creator, whom I call the 'Lord God.'

An object in motion tends to remain in motion along a straight line unless acted upon by an outside force.

As a blind man has no idea of colors, so have we no idea of the manner by which the all-wise God perceives and understands all things.

Atheism is so senseless. When I look at the solar system, I see the earth at the right distance from the sun to receive the proper amounts of heat and light. This did not happen by chance.

Fidelity and allegiance sworn to the King is only such a fidelity and obedience as is due to him by the law of the land; for were that faith and allegiance more than what the law requires, we would swear ourselves slaves and the King absolute; whereas, by the law, we are free men, notwithstanding those oaths.

Genius is patience.

God is the same God, always and everywhere. He is omnipresent not virtually only, but also substantially, for virtue cannot subsist without substance.

God made and governs the world invisibly, and has commanded us to love and worship him and no other God; to honor our parents and masters, and love our neighbours as ourselves; and to be temperate, just, and peaceable, and to be merciful even to brute beasts.

Gravity may put the planets into motion, but without the divine Power, it could never put them into such a circulating motion as they have about the Sun; and therefore, for this as well as other reasons, I am compelled to ascribe the frame of this System to an intelligent Agent.

Hypotheses should be subservient only in explaining the properties of things but not assumed in determining them, unless so far as they may furnish experiments.

I do not know what I may appear to the world, but to myself I seem to have been only like a boy playing on the seashore, and diverting myself in now and then finding a smoother pebble or a prettier shell than ordinary, whilst the great ocean of truth lay all undiscovered before me.

I have a fundamental belief in the Bible as the Word of God, written by those who were inspired. I study the Bible daily.

I have explained the phenomena of the heavens and of our sea by the force of gravity, but I have not yet assigned a cause to gravity.

If a projectile were deprived of the force of gravity, it would not be deflected toward the earth but would go off in a straight line into the heavens and do so with uniform motion, provided that the resistance of the air were removed.

If the experiments which I urge be defective, it cannot be difficult to show the defects; but if valid, then by proving the theory, they must render all objections invalid.

In experimental philosophy, we are to look upon propositions inferred by general induction from phenomena as accurately or very nearly true, notwithstanding any contrary hypotheses that may be imagined, till such time as other phenomena occur by which they may either be made more accurate or liable to exceptions.

In the absence of any other proof, the thumb alone would convince me of God's existence.

In the beginning of the year 1665, I found the method of approximating series and the rule for reducing any dignity of any binomial into such a series.

Infinites, when considered absolutely without any restriction or limitation, are neither equal nor unequal, nor have any certain proportion one to another, and therefore, the principle that all infinites are equal is a precarious one.

It may be that there is no such thing as an equable motion, whereby time may be accurately measured. All motions may be accelerated or retarded, but the true, or equable, progress of absolute time is liable to no change.

Just as the system of the sun, planets and comets is put in motion by the forces of gravity, and its parts persist in their motions, so the smaller systems of bodies also seem to be set in motion by other forces and their particles to be variously moved in relation to each other and, especially, by the electric force.

My powers are ordinary. Only my application brings me success.

Opposite to godliness is atheism in profession, and idolatry in practice. Atheism is so senseless and odious to mankind, that it never had many professors.

Plato is my friend; Aristotle is my friend, but my greatest friend is truth.

Religion and philosophy are to be preserved distinct. We are not to introduce divine revelations into philosophy, nor philosophical opinions into religion.

That the divided but contiguous particles of bodies may be separated from one another is a matter of observation; and, in the particles that remain undivided, our minds are able to distinguish yet lesser parts, as is mathematically demonstrated.

The Ignis Fatuus is a vapor shining without heat.

The centre of the system of the world is immovable.

The description of right lines and circles, upon which geometry is founded, belongs to mechanics. Geometry does not teach us to draw these lines, but requires them to be drawn.

The moon gravitates towards the earth and by the force of gravity is continually drawn off from a rectilinear motion and retained in its orbit.

The proper method for inquiring after the properties of things is to deduce them from experiments.

The same thing is to be understood of all bodies, revolved in any orbits. They all endeavour to recede from the centres of their orbits, and were it not for the opposition of a contrary force which restrains them to and detains them in their orbits, which I therefore call Centripetal, would fly off in right lines with a uniform motion.

There are more sure marks of authenticity in the Bible that in any profane history.
