The human is not a machine equipped only with an intellect. We are far more advanced than that. Beyond the 5 senses are the feeling senses which work more subtly. We must "tune into" this part of our nature to gain the insights this part of us presents.
Those who engage only the intellect to understand life or part thereof are not connecting in any real way with that which they study. For that to occur we must place our attention on the thing itself (not the thought of the thing) and, without thinking, pay attention to feelings it evokes within us.
This will tell us more about our focus of attention than a never ending process of deductive reasoning ever could!
