Philosophy relies on esoteric assumptions without any basis in reality.

Certain assumptions are philosophically undeniable, such as the “real” laws of logic.

Philosophy cannot yield absolute certainty, it is only a speculative pursuit.

Most fields of study, including science, do not yield absolute certainty, yet we accept them as valid and beneficial disciplines. Philosophy does yield certainty in many areas, such as the nature of logic, truth, and self-existence, since to deny any of these would rationally be tantamount to affirming them.

Philosophy is not verifiable through observation or experience.

Nor is this objection even though the objection does not have meaning and value to the one making the objection.

Philosophy in apologetics has no practical value. Nor does it promote one’s godly character. What do you do with it?

This objection makes the mistake of assuming that if something is not usable in practical terms, then it is of no value. But there are many things the philosopher can “do”: think clearly, evaluate literature to avoid deception, make wise decisions, teach, and be a better person as a result of thinking properly. 

The apostle Paul warned the church when he said “Beware lest anyone cheat you through philosophy  and empty deceit”. (Colossians 2:8)

Most likely Paul was speaking about a particular philosophy (probably an incipient (Gnosticism) since the Greek text shows the definite article (tas, the) directly preceding the word “philosophy.” Paul is speaking of a negative kind of philosophy characterized by “the tradition of men” the basic principles of the world” and “ not according to Christ”.

The discipline of philosophy has secular (Thales, Heraclitus, Socrates, Plato, Aristotle) and pagan origins (Oracle of Delphi) and should be avoided.

One who rejects truth or a discipline of study simply because of its origins commits the “Genetic Fallacy.” If this objection is true, then many beneficial aspects of medicine, science, mathematics, education, and logic should be avoided (e.g, Philippians 4:8).

Empirical science offers a higher degree of certainty since it is visually based and can be repeatedly tested in order to confirm results.

Even empirical science has philosophical elements that cannot themselves be discovered or supported through use of the scientific method, such as knowledge, logic, morality, and being. To deny these nonempirical realities would be to undermine empirical science.

Philosophy elevates reason over the Bible and makes mankind instead of Scripture the test for truth.

Prior to salvation, reason must be used to evaluate the truthfulness of religious literature. After salvation, one’s thinking must be in accord with, and submitted to, God’s revelation in the Bible.
