When you start thinking you truly become frightened?

Many people hate insecurity and doubt. They think fixed values and invariable rules are a guarantee to happiness.

Spinoza is a philosopher whose image of human weakness and foolishness is without illusions, but who at the same time feels we are gifted with something that can improve our fate - our ability to think and investigate. 

Since Spinoza believes in only one reality, all phenomenons are equally ‘real’. Therefore, we should investigate our desires and feelings as seriously as we would investigate gasses and strata. Our ideas about good and bad, real and fake, will change because of this thinking and investigating. In the acceptance of the logic of nature lies our freedom and biggest chance at success. 

For Spinoza, holding on to uncritically investigated views is a recipe for unhappiness, conflict, disaster.
