Becoming Wise or Rational
Reason means you have the capacity to solve issues. Wisdom is a state of being, while being Rational is an activity. Reason can be the trait of a child while Wisdome can only be the trait of someone with experience. To be rational means to draw good conclusions and to make good decisions. Reason is like flowing water, wisdom is like deep sea water. Reason is active, wisdome is profound.
The shortcomings of reason are that one can sometimes forget the big picture. It would help to be a little wise(/profound) so this doesn't happen. The shortcomming of wisdome is the fact that you can become passive to the fenomena of life. Reason is in fact puting pieces together, while wisdom is to hold on to what you know (or to know without thinking). Reason makes room for logic and thought, while wisdom means to base your decisions on your prior experience. This is why babies can't be wise. Reason is the beauty of THINKING while Wisdom is the beauty of DOING.
Femininity is characterised by reason while Masculinity is characterised by wisdom. That is why a woman will always be found talking while a man will inclined to do things. Reason is logic, Wisdom are deeds. The trait of a wiseman is a good memory, while the traits of a rational man is logic.
So to resume: if you want to resolve problems you must become a man of reason and put pieces together, establish conections between things, make use of logic. While the key to become Wise is to live by what you already know without thinking.
