A Quote by Carl Sagan

[Science] is not perfect. It can be misused. It is only a tool. But it is by far the best tool we have, self-correcting, ongoing, applicable to everything. It has two rules. First: there are no sacred truths; all assumptions must be critically examined; arguments from authority are worthless. Second: whatever is inconsistent with the facts must be discarded or revised. ... The obvious is sometimes false; the unexpected is sometimes true.

There is no other species on Earth that does science. It is, so far, entirely a human invention, evolved by natural selection in the cerebral cortex for one simple reason: it works. It is not perfect. It can be misused. It is only a tool. But it is by far the best tool we have, self-correcting, ongoing, applicable to everything.

Carl Sagan

Science is not perfect. It's often misused; it's only a tool, but it's the best tool we have. Self-correcting , ever changing, applicable to everything: with this tool, we vanquish the impossible.

Carl Sagan

I am more fond of achieving than striving. My theories must prove to be facts or be discarded as worthless. My efforts must soon be crowned with success, or discontinued.

Carolyn Wells

I never go online on my iPhone. Sometimes I'm tempted but I remind myself and the kids - it's a tool. Use it as a tool. You're not the tool. My iPhone, 85% of the time I'm writing down ideas.

Matthew McConaughey

To be worthy of the name, an experimenter must be at once theorist and practitioner. While he must completely master the art of establishing experimental facts, which are the materials of science, he must also clearly understand the scientific principles which guide his reasoning through the varied experimental study of natural phenomena. We cannot separate these two things: head and hand. An able hand, without a head to direct it, is a blind tool; the head is powerless without its executive hand.

Claude Bernard

The market is a tool, and a useful one. But the worship of this tool is a hollow faith. Far more important than any tool is what you make with it.

Eric Schlosser

We all make basic assumptions about things in life, but sometimes those assumptions are WRONG. We must never trust in what we assume, only in what we KNOW.

Darren Shan

You must understand that violence in a movie is only a tool. If it's used badly, it will be horrible. If it's used correctly, it can be very interesting. But, essentially, it's just a tool.

Nicolas Winding Refn

The intentions of a tool are what it does. A hammer intends to strike, a vise intends to hold fast, a lever intends to lift. They are what it is made for. But sometimes a tool may have other uses that you don't know. Sometimes in doing what you intend, you also do what the knife intends, without knowing.

Philip Pullman

In science one must search for ideas. If there are no ideas, there is no science. A knowledge of facts is only valuable in so far as facts conceal ideas: facts without ideas are just the sweepings of the brain and the memory.

Vissarion Belinsky

To make the best use of your life, you must never forget two truths: First, compared with eternity, life is extremely brief. Second, earth is only a temporary residence. You won't be here long, so don't get too attached.

Rick Warren

You must accept that if the computer is a tool, it is the job of tool user to know what to use it for.

Peter Drucker

If you believe certain words, you believe their hidden arguments. When you believe something is right or wrong, true or false, you believe the assumptions in the words which express the arguments. Such assumptions are often full of holes, but remain most precious to the convinced.

Frank Herbert

There’s an assumption that if someone writes in the first person it’s self-indulgent and self-regarding. I just look at it as a tool to understand the world and my experience in it. It’s not a tool to understand myself.

Michael Pollan

There must be only three supreme values which govern a person's life: Reason, Purpose, and Self-esteem. Reason, as his only tool of knowledge--Purpose, as his choice of the happiness which that tool must proceed to achieve--Self-esteem, as his inviolate certainty that his mind is competent to think and his person is worthy of happiness, which means: is worthy of living. These three values imply and require all of man's virtues, and all his virtues pertain to the relation of existence and consciousness: rationality, independence, integrity, honesty, justice, productiveness, pride.

Ayn Rand

No doubt science cannot admit of compromises, and can only bring out the complete truth. Hence there must be controversy, and the strife may be, and sometimes must be, sharp. But must it even then be personal? Does it help science to attack the man as well as the statement? On the contrary, has not science the noble privilege of carrying on its controversies without personal quarrels?

Rudolf Virchow
