Berkeley remarked that the basis of the matter is the assumption that we can, apart from the particular properties of things, form the abstract idea of the common for all of them material as a kind of substrate. However, according to Berkeley, it is impossible: we do not have the sensory perception of matter; our perception of each item is expanded without any residue on the perception of a certain sum of individual sensations or ideas. Indeed, in this case there will nothing remain from the matter: it seems to be dissolved in some “fog” of uncertainty, which in general can not influence anything. So, here is an aphoristic postulate of Berkeley: “To be – means to be in perception.”The philosophical ideas of Berkeley and his atheist position lead us to the following conclusion. If there is no God, then the things we consider the material objects must have a spasmodic life: suddenly emerged at the moment of perception, they immediately would disappear as soon they leave the field of view of the perceiving subject. But, Berkeley argued that due to the constant vigil of God, everything in the world (trees, rocks, crystals, etc.) exists constantly, as a good sense befits. Berkeley was an outstanding writer, who had an elegant style (by the way, his numerous works he wrote when he was 28!). He was not only a priest (Bishop in Cloyne,Ireland) and a philosopher but a psychologist also.Berkeley tried to prove that we perceive only the properties of things: how these things affect our senses, but we do not grasp the very essence of things, even though the properties are relative to the perceiving subject. Sensory impressions are the phenomena of the psyche.
