Hello Magurk,
You said:
For a while now i have been a preety strong aethiest.
I currently have been reading works of plato and socrates and other famous philosophers and started asking myself, should i really give up on faith? I've been thinking about going back to temple(jewish) with my family and start worshiping again. I only have been thinking about this because i also asked the question, what if your wrong Eric? About the afterlife. I thaught when you die well you just die, but picking up these works and just thinking much more about it i face the possibility that im wrong, and come my death what then?
Any of you have suggestions for me?
Geez Magurk. There's nothing quite like presenting a complex question that lends no snappy or simple answer in reply. ;-)
I'll assume from your other posts within REF that you are still in secondary (High school) education (still time to polish those typing/spelling skills ;-)). If this is so, I applaud your interest in reading (and pondering upon) some of mankind's most notable philosophers. Not many folks of your generation indulge the ruminations of great thinkers of the ages. I encourage you to continue discovering as many varied and divergent philosophical works as time and opportunity may afford you.
"Strong" atheism is not for the weak of heart, the intemperate, or for the unsure. Atheism is not about "denying" the claims of supernaturalistic/theistic beliefs. Atheism is a confidently and self-assured rational position, stating that claims of supernatural cause/effect "explanations" of natural phenomena are simply not credible "beyond a reasonable doubt", when such claims are unsubstantially evidenced or inherently unfalsifiable/unprovable. Do you question the veritable existence of the Easter Bunny, fairies, or hobgoblins? Is your position regarding these myths/legends that they are unequivocally unsubstantiated bunk; or "possible, but unproven"? If your position is of the former, then you may be a "strong atheist" ("Beyond a reasonable doubt, I conclude that there is no Easter Bunny"). If it is the latter, you may be more likely an agnostic (or some form of spiritualist instead ("There may or may not be a God. I don't know/don't care/unsure/undecided").
Just so you know, I have been both an ardent skeptic and a "strong atheist" my entire adult life (30+ years). As such, I would counsel that you exercise your critical thinking and reason in all aspects of merited evaluation, consideration, and resultant choices. Would you abandon critical evaluation of available data when considering a purchase of an mp3 player, cell phone, or new CD/DVD? Which do you "trust" most? Your "gut instinct"; peer pressure; popular/majority opinion; or facts and evidences that lead to a thusly rendered rational, informed, and "reasonable" conclusion? When you're a teenager, it's difficult (practically impossible) to ignore/dismiss external pressures that seek to "guide" you to a predetermined/forgone assumption/conclusion. Nobody wants to be perceived as dating the "fat or homely" girl, even if you don't see her as being either fat or ugly.
As a reminder, atheism makes no promises as to any benevolence within the cosmos. In fact, from an atheistic view, the cosmos is absolutely ambivalent about your momentary existence in the grand scope of things in time. The universe lends neither punishment nor reward - only consequences in choices made or unmade. No "ultimate justice". No "higher plane of existence". No "milk and cookies" for "being good". No "fire and brimstone" for "being bad". The cosmos just is...and you have the momentary opportunity to experience a mortal existence to it's fullest. You establish (through experience, knowledge, and personal discovery) your own "purpose" for existence; your own "reason" to exist. This "freedom" to choose your own course is not without responsibility/accountability. As an atheist, you have no deity/force to either blame or gratefully acknowledge for your fortunes and choices. No shaking your fist at the sky. No wishful thinking to ameliorate difficult circumstances. It's your bed...you made it...and you're gonna have to sleep in it.
Now, if the prospect of being fully free, yet fully accountable for all of the choices you make, conclusions you draw, and behavior/actions you concomitantly assume responsibility for as solely your your own answer for...makes you uneasy, uncomfortable, or noncommital...then perhaps a declaration of professing "strong atheism" is a tad premature, or at least mischaracterizing of your tenuous (and prospectively fluid) personal philosophy. But take heart. Some folks spend their entire adult lives in ongoing quests - seeking those seemingly elusive, immutable, spiritual, and definitive "truths" of a mortal existence. Some will rely upon logic/reason/skepticism to discern such "truths". Far more will accept abstract premises/claims predicated upon "faith" alone as definitive allegorical/philosophical/dogmatic "truths".
The bad news is...you have to make those determinations of "truth" for yourself.
The good news is...you have a mind of your own to use, to the best of your own abilities, in making such determinations.
You have suggested the "conundrum" of "Pascal's Wager", which posits (in essence) "What have you got to lose by believing in (a) god? If you're 'right', then no harm done. But if you're wrong, you'll suffer eternal unpleasant circumstances."
Simple enough, right? Seems a logical enough conclusion to accept, doesn't it? But such is the stuff of logical fallacies, and why they hold no water or merit when exposed to the light of reason and critical evaluation. If you like, here are some critical refutations of "Pascal's Wager", and why "worrying" about the (implied/inferred/threatened) prospective untoward consequences of "unbelief" are fallacious and unmerited by simple implementation of rational thought.
