Quote of the Day by René Descartes: “It is not enough to have a good mind; the main thing is to use it well.”

Meaning of the Quote of the Day by René Descartes

This quotation was made by René Descartes in the 17th century in his work Discourse on the Method where he attempted to provide advice on clear thought and true knowledge. 

Essentially, the quotation suggests that simply being intelligent is not enough; the critical thing about intelligence is how it is used. 

In order to “use it well,” an individual needs to think intelligently, be curious, remain patient, and take reasonable actions. 

Therefore, when speaking of the good mind, one should not only mean intelligence, memory, and ability to think quickly but also ability to think intelligently.

  1. The essence of the above-mentioned quotation can be interpreted as follows:

  2. Intelligence without direction can lead to mistakes or wasted time.

  3. To use one’s mind well is to plan things, reflect over them, and try to view them from different angles.

  4. This quotation implies that one should think actively rather than wait for thoughts.

This way, the author stresses a particular behavioral strategy that people should practice.

Why Is This Quote of the Day by René Descartes Relevant Today?

The quote of the day makes perfect sense in our current environment with abundant sources of information, social networks, and instantaneous judgments. 

Put simply, it implies that a phone full of opinions and facts means nothing if you never use your judgment to consider the source, think for yourself, and make an informed decision. 

Emotionally, the quote may apply when you feel enraged by some news you've read. Using your mind effectively, you will be able to pause and see whether you should be angry or not.

The quote of the day can be applied to today's world in:

  1. Education/Work: instead of immediately giving your opinion on a topic or problem, you will analyze your actions.

  2. Social Media/Digital Communication: before posting or commenting on anything, you will pause and use your brainpower.

  3. Personal Development: instead of doing something because everybody else does it, you will reflect.
