Rationalism describes any philosophy that claims that beliefs and opinions should always be logical, deductive conclusions rather than being based on experience, observations, religious teachings, or divine revelation.

Keywords: Rationalism, Philosophy, Logical, Reasoning, Deductive, Experience, Observations, Religious, Revelation, Contradictory.


Rationalistic claims are false .


All self-refuting or contradictory claims are deductively false.

Premise 1: Only deductive conclusions should be believed.

Premise 2: Premise 1, being the foundation or starting point of the philosophy, is not itself a deductive conclusion.

Conclusion: Therefore, premise 1, also known as "rationalism", should not be believed.

Rationalistic claims, when adhered to, require the rejection of rationalistic claims. To accept them is to reject them, making rationalism inherently contradictory and deductively false.

"Does the "problem of evil" show that an all-good, all-powerful, all-knowing god cannot exist?"

The "problem of evil" generally goes something like this. 1. If God had all-power over our universe, he would have been able to prevent the wickedness of Adolf Hitler. 2. If God had all-knowledge of our universe, he would have known how to prevent the wickedness of Adolf Hitler. 3. If God were all-good, he would have wanted to prevent the wickedness of Adolf Hitler. 4. Adolf Hitler was wicked in our universe. 5.

"What does 'moral' mean? Why be moral?" defines "moral" as "of, pertaining to, or concerned with the principles or rules of right conduct or the distinction between right and wrong". Whenever we look at morality in a forum such as this, it is always helpful to present what is generally known as the "Moral Argument for the Existence of God". Briefly put, if an absolute and moral God does not exist, then objective moral values do not exist.

"Why should one believe in the validity of the Bible?"

Much could be said about manuscript evidence (demonstrating conclusively that the Bible has been reliably passed down to us), archaeological evidence (demonstrating that the locations, lifestyles, and many of the people in the Bible are genuine), eyewitness testimonies and changed lives (demonstrating the genuine sincerity of the authors, such as the apostles Peter and Paul, who were executed for their claims), and fulfilled prophecies (such as Daniel 9:24-25, Leviticus 26:44, Jeremiah...

"Can there be objective morality with a God? If God is the source of morality, then morality is subject to the will of God, so isn't it by definition subjective?"

There can only be objective moral values with God. When we state that objective moral values exist, what we mean is that there are moral values that govern all humans, regardless of whether or not those humans want those values to govern them, like those values, or accept those values. If moral values were the result of popular vote, then they would only govern humans because humans had decided to allow them to govern them. Then moral values would not be objective, but rather, subjective.
