Human are different from animals because of their capability to rationalise things. In being rational, they can aspire to be higher than just a surviving species; they can realise things. In this, humans can dream, have a goal and fulfil themselves according to their capabilities.
With their current capabilities, humans achieve great achievements. However, dreams can elevate to higher places. Realising their incapability, humans will try to improve their capabilities, a stepladder towards their own goal.
However, some stepladders tend not to be enough, and humans can fail. When they fail, this is when they try harder, with passion for their dream. With enough tries, a human fails, and this is where a “safety net” of ideologies will take hold of them.
This is how philosophy interacts with a human’s dreams and aspirations. Philosophy tries to explain the human nature, majority of which when failure is tantamount. However, philosophy does not hold the answer, only another picture, and sometimes, it leads to the cynicism of an individual.
A human must remember that their rationality is the springboard to their dreams, and if they rationalise the realities with absurdities too often, they may end up being dreamless, reverting only to survive, rather than fulfil. They may also decide to just remain in one single place where they realise their dreams cannot be fulfilled, and the absurd is constant.
It is human nature to dream, and to stop it is to stop being human. Philosophy is only a guide, but in the end, it is the choice of the human to see their capabilities, and what they need to do to fulfil their goals, no matter how ambitious or unrealistic it may seem.
