Prabhupāda: So far I remember—I was also a student of philosophy—Dr. Urquhart, he said the philosophy is science of sciences. The science, their, I mean, theory begins from philosophy. Philosophy is the science of sciences. But according to Vedic version, a philosopher is not a philosopher if he has not a different opinion from another philosopher.
Nasau munir yasya mataṁ na bhinnam. Therefore, through the philosopher you cannot come to the right conclusion. Tarko apratiṣṭhaḥ. If you simply go on arguing, that will also not help you. If you simply read scriptures, that will also not help you. Because there are different scriptures. Bible is different from Vedas, and Vedas is different from Koran.
So tarko apratiṣṭhaḥ (CC Madhya 17.186), by argument you cannot come to the conclusion. By simply reading scriptures you cannot come to the conclusion. By following the philosophers you cannot come to the conclusion. Therefore the truth is very confidential. Dharmasya tattvaṁ nihitaṁ guhāyāṁ. It is kept very confidential. Then how to have it? Mahājano yena gataḥ sa panthāḥ (CC Madhya 17.186): you have to follow the great personalities who have actually realized God. That is the conclusion.
