and that purpose is to reach some goal (e.g. a seed's purpose is to reach the goal of sprouting a tree, and the tree's purpose is to make air/feed animals)
so every purpose achieves a goal and that goal has a purpose itself to achieve another goal... won't the chain (of purpose->goal->purpose etc.) evetually end and there will be no purpose? or will it stretch onto infinity... if it does what's the purpose of the chain?
