Philosophy is what is formed of the essential determination of thought. Essentially an idea exists for self-determination that it weighs as truth.The element of Philosophy is not abstract or non-actual but it is formed through abstractions though that the abstract thought has refined itself in the instantiation of something actual and moving from non-actual to actual we reach at the conclusion which forms the nerve of Philosophy. This whole movement constitutes what is the truth in Philosophy whether it is the idea of time or of being or of time and being. In either case, we begin with abstract non-actuality of time existing as discrete quanta and moves on to the exact instantiation of time as happening at a particular moment, So it is the appearance of time in the form of event in the time-space continuum that we confront that what has in effect brought in itself as truth.
From actual, we proceed to the knowledge of the self, the inherent seed of Brahman existing in nutshell as the unity of cosmos.The true is thus revealed to us in the form of knowledge of the self that we have moved or become actual from non-actual.So, in the end, we have determinate thoughts taking shape in the form of self-knowledge.
