Quote by Niccolo Machiavelli
There are three kinds of intelligence: one kind understands things for itself, the other appreciates what others can understand, the third understands neither for itself nor through others. This first kind is excellent, the second good, and the third kind useless.
Summary
This quote asserts that there are three types of intelligence. The first type is characterized by the ability to comprehend and understand things independently. This level of intelligence is considered excellent. The second type of intelligence is defined by one's capacity to appreciate the understanding of others. Though not as exemplary as the first type, it is still deemed good. Finally, the quote suggests that there is a third and inferior kind of intelligence, which is unable to understand things on its own or through others, rendering it useless.
