A deficient number is a positive integer that is greater than the sum of its proper divisors (excluding itself). In other words, the sum of the proper divisors of a deficient number is less than the number itself. For example, the number 8 is a deficient number because the sum of its proper divisors (1, 2, 4) is less than 8. Deficient numbers are contrasted with perfect numbers, where the sum of the proper divisors equals the number, and abundant numbers, where the sum of the proper divisors exceeds the number. **

According to Arnold Gehlen, animals are neither deficient beings nor cultural beings. Gehlen argues that animals are not deficient because they are well-adapted to their environments and have their own unique ways of interacting with the world. At the same time, he also argues that animals are not cultural beings because they do not possess the capacity for symbolic communication and the creation of complex social structures. Instead, Gehlen sees animals as existing in a middle ground between deficiency and culture, with their own distinct mode of being in the world. **
