A philosopher, Benedictus Spinoza, who lived between 1632 and 1677, said: “by substance I understand what is in itself and is conceived through itself, that is, that whose concept does not require the concept of another thing, from which it must be formed” (Law, 2007: 77). Thus, understanding the original, pure thought process. The impact on education suggests that substance would be the basis of all knowledge and that all theory and further human learning stems from this base.
