It
is a notable fact  from comprehensive on
the nature of philosophy that the subject 
is comprehensive, that is all 
inclusive. All disciples, field of knowledge, were included in subject of
philosophy. Moreover, the subject is interested in the whole of reality it does
not like the other discipline isolate an aspect of reality to study, rather it
studies reality in its totality. In effect, philosophy is interested in he
knowledge and the significant of the knowledge or phenomena that is not limited
by the boundaries of some specialized field of human activity. 
The philosophic
worldview is thus a theoretical synthesis of the most general views of nature,
society, man and cognition (Oysterman 1973:179). This means that philosophy is
an integral system of intellectual  
attitude in which the desire for absolute knowledge is organized
methodically.PHILOSOPHY IS CRITICAL
There is indeed no one idea or thing that is taken as
given and therefore unquestioned in philosophy. Every idea, opinion, view etc
is subject to doubt, question and critical analysis. In philosophy, no answer
is definitive, and turns out to be the basis for further changes directed at
philosophy augmentative at philosophy are indeed character result of its
critical philosophy does not discriminate in the choice of subject matter, it
is concerned with reality in its totality, it is concerned such, there are
changes an avalanche of questions it never arrives at a once and for all accepted
answer. No answer can put an end to the philosophical inquiry since every
answer out to be new question.
Philosophy is open, not dogmatic, it engenders and
nourishes itself through question and argumentation. Nothing is indeed
sacrosanct, in fact, according to “Bertraind’ there no knowledge that is no
certain that we cannot question or doubt. (Rene Descautes) a French
philosophy  and scientist  exemplified this when he doubted his own
existence, philosophy is a study effect through questioning , reflection,
analysis and  argumentation, the
subject  review, re-examine every  issue of life. Philosophical wisdom, john
pass more, says is grounded in cross examination. 
ANALYTIC
Analytics is a 
systematic procedures for 
providing  results. To
analyze  a thing is to break it down  to its 
constituent   parts in order
to  determine their relationship and value  
IMPORTANT OF PHILOSOPHY TO PRACTICAL
LIFE AND HUMAN DEVELOPMENT
            Philosophy
as concern with human existence undoubtedly deals  with the 
deepest problem  and issues of a
man  and his existence. Philosophical
problem  Koroner,  said, are those problem  that arise in the cause of trying  to 
master  difficulties  in cognition 
However,
this legendary problem associated with  
the definition of philosophy 
ordinarily, is an all  embracing
discipline, it covers both the humanities and the science  at the out set,  the whole field of  knowledge 
(learning)  everything behold
reading  writing and arithmetic  was included 
in  the  subject of 
philosophy. 
Philosophy is the mother of all subject . indeed,
philosophy , was the  only  subject available to give answers  to  the
fundamental  questions arising  from the universe and its contents.  
The  point is
that, philosophy is  parental discipline
from  which with the development of
humanity in process of learning and knowledge acquisition, kind of  “erupted’ such that various branches  of knowledge disengaged  from it to form  organized and systematic separate field of
specialized knowledge.
This  rather centrifugal
movement of various braches of knowledge  
from philosophy  is only
indicative of mans acquisition of more extended 
and better assured knowledge of classification  of phenomena 
   In fact, that various specialized
disciplines are only regional ontologism by their orientation and character;
they deal only with fragment of knowledge hence, can only give in sufficient
and penultimate of account of knowledge. For them to see knowledge in its
whole, they have to go back to (their parent) philosophy the only discipline
that aims at understanding the quintessential and the universal in everything
that exists.
The ultimate reality that philosophers seek to know is
in contrast to the every day things of this world truly, self contained and
could accordingly, be looked upon as self caused. To arrive at does full
justice in explaining that is. The point is that we cannot explain things
satisfactorily if we remain within the world of common sense or even if one
advances from that world to embrace the world of science.
In conclusion, important of philosophy to practical
life and human development is that philosophy is as love of wisdom means a
continuous search for wisdom, the pursuit of wisdom not for gains but for its
own sake. 
Wisdom is higher than 
knowledge aptly shown by Aristotle(1966:5T5-57)  according to 
him, that  all men desire  to know different degree of  knowledge, Aristotle  also 
view,  that  highest wisdom does not  aim at producing  anything or securing some effect, but at  apprehending 
the first principles of  reality.
Philosophy to practical life and 
development concern with all legitimate thinking of how man lives in
this  would  rather than  
with the ultimate nature  of being
man is a centre of all thinking  he is
active and  creative, he might  be other than he is, man makes his essence as
he goes along. He is indeed, the focus of all activities (accoding jean  Paul Sartre ) 
Finally philosophy helps in development of humanity
in  acquisition  of wisdom 
and knowledge through reasoning,  matters affecting human fate  and  
conduct in the most basic  way.
