The Murkey Notion of Numeral One by Sherif S. Monem

The concept of "One" is invariably successfully used in our lives. However, in absolute sense there is no thing can be called one. To call something one you have to define it very precisely and there is no such thing. So say one tree and then if you take all the branches will it be still a one tree? if you chop it will it be a one tree? if you keep chopping will it remain a one tree? Another example one Child, how old when he/she have changed from a child in common meaning from baby and how old for child to be called an adult in pure sense.
How much you can take from body of car to still be called one car.
So the concept of one in absolute sense is vague and just a notion.
