Quote by Leonardo da Vinci
He who loves practice without theory is like the sailor who boards ship without a rudder and compass and never knows where he may cast.
Summary
This quote suggests that engaging in practice without a solid understanding of theory is a futile endeavor. It compares such a person to a sailor who sets sail without a rudder and compass, lacking direction and purpose. Without theory as a guiding force, the person's actions may lack coherence and lead to unpredictable outcomes. The quote implies that a combination of both theory and practice is necessary for success and the ability to navigate through life's challenges.
