Quotes by Pierre-Simon Laplace

The universe is a grand book, which cannot be understood unless one first learns to comprehend the language and interpret the characters in which it is written. It is written in the language of mathematics.

Often attributed to Galileo, but the sentiment aligns with Laplace's deterministic view.

The human mind is a machine for drawing conclusions from premises.

General quote attributed to Laplace

The greatest advantage of mathematics is that it allows us to reason about things that we cannot see or touch.

General quote attributed to Laplace

The more we know, the more we realize how much we don't know.

General quote attributed to Laplace

The true scientist is a perpetual student.

General quote attributed to Laplace

The laws of probability are the laws of common sense.

General quote attributed to Laplace

The future is uncertain, but the past is fixed.

General quote attributed to Laplace

The universe is a clockwork mechanism, and we are merely cogs in the machine.

General quote attributed to Laplace, reflecting his deterministic worldview.

The only thing that is constant is change.

Often attributed to Heraclitus, but a sentiment that could be applied to Laplace's understanding of celestial mechanics.

The human mind is a slave to its passions.

General quote attributed to Laplace

The greatest discoveries are often the simplest.

General quote attributed to Laplace

We may regard the present state of the universe as the effect of its antecedent state and as the cause of the state that is to follow. An intellect which at a certain moment would know all forces that set nature in motion, and all positions of all items of which nature is composed, if this intellect were also vast enough to submit these data to analysis, it would embrace in a single formula the movements of the greatest bodies of the universe and those of the tiniest atom; for such an intellect nothing would be uncertain and the future just like the past would be present before its eyes.

The most important questions of life are, for the most part, nothing but problems of probability.

A Philosophical Essay on Probabilities 1814

It is an excellent thing to know the order of the universe and to be able to predict the phenomena which it presents to us.

Unknown

We are so far from knowing all the forces of nature and the different ways in which they act, that it would be unphilosophical to deny phenomena solely because they are inexplicable in the present state of our knowledge.

Unknown

The more profound our knowledge of the laws of nature, the more we are convinced that everything is determined by them.

Unknown

The human mind has been able to understand the laws of the universe, and to predict the phenomena which it presents to us.

Unknown

The universe is a vast machine, the movements of which are determined by immutable laws.

Unknown

It is difficult to give a satisfactory definition of probability.
