According to Oxford: (or at least thier dictionary)
Faith~ A complete trust or confidence in someone or something. A strong belief in a religion. A system of religious belief. Origin from the latin fides.
Science~ A systematic study of the structure and behaviour of the physical and natural world through observation and experiment. An organized body of knowledge on any subject. Origin from the latin scientia.
Fides in latin stands for trust, faith, confidence, relience etc etc.
Scientia in latin stands for knowledge, skill, expertise etc etc.
You need both as a human being. They are two sides of "our" coin. One leans to the heart, the other to the mind. Regardless of what your "faith" is in you do in fact have it.
A careful study of the history of religion and science will show one that they do in deed look for and claim to have the answers to many of the questions that have plauged humanity. (The who, what, why, where, hows, of it all.)
Both are very secular in the structure, yet use far different approaches to thier systems. Believe it or now both look internally as well as externally for thier information. If I am not inspired to make a hypotheisis how can I set up an experiment? If I am not able to see the wonders of existence and measure them how can I quantify what is observed and understand it?
Or mabey Darth Vader said it best. You shouldn't put "all" your faith in this technological monstrosity, it's power pales in comparisson to the power of the Force.
Or as Robert Oxton Bolton once said: " A belief is not merely an idea the mind possesses; it is an idea that possesses the mind."
