Both animals and humans congenitally have basic needs for food, water, and communication with their own kind. If these needs are not met, then neither the animal nor the person will be able to live. During a person’s life, secondary needs are also formed (the desire to dress beautifully, listen to your favorite music, etc.). Secondary needs can be very diverse, and they depend on the individual characteristics of a person, and on the environment that surrounds him in life, and on material capabilities. Needs can be material (the desire to feast on the cake), and spiritual (the desire to go to a new exhibition of painting, the desire to compose poetry or music).
Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
